If you are shopping for an affordable backpacking tent, the Mountain Warehouse Backpacker 3 is likely to appear on your shortlist. It promises something that sounds especially appealing to new hikers: three-person capacity, a relatively low 2.7 kg packed weight, aluminum poles, taped seams, and a compact packed size—without the price tag typically associated with premium backpacking shelters.
But there is an important question behind the specifications:
Is the Mountain Warehouse Backpacker 3 actually a good backpacking tent, or is it simply a cheap tent that happens to be portable?
After years of camping, backpacking, trekking, and testing outdoor equipment, I think this distinction matters. A tent can be inexpensive, spacious and reasonably light while still having compromises in weather protection, ventilation, durability, and long-term livability.
This review takes a practical look at the Mountain Warehouse Backpacker 3, including its weight, space, waterproofing, setup, ventilation, materials, durability, backpacking performance, and value.
The short version?
Yes, the Backpacker 3 can be worth buying—but only if you understand what it is designed to do. It makes the most sense for budget-conscious campers, summer backpackers, festival trips, beginners, and relatively mild three-season conditions. It is less convincing if your priorities are ultralight weight, severe weather performance, premium durability, or extended backcountry trips.
Mountain Warehouse Backpacker 3: Quick Review
Before getting into the details, here is the practical overview.
| Feature | Mountain Warehouse Backpacker 3 |
|---|---|
| Capacity | 3 people |
| Packed weight | Approximately 2.7 kg / 6 lb |
| Packed size | Approximately 51 × 20 × 20 cm |
| Pitched dimensions | Approximately 300 × 240 × 105 cm |
| Waterproof rating | 2,000 mm hydrostatic head |
| Poles | 7001 aluminum |
| Construction | Single-skin design according to current product information |
| Seams | Taped seams |
| Best use | Budget backpacking, trekking, summer camping |
| Biggest strength | Space-to-price ratio |
| Biggest weakness | Weight and weather/durability compromises compared with premium backpacking tents |
My overall assessment: 7.5/10 for the right buyer.
That score could be higher or lower depending on your expectations.
For a beginner buying a first backpacking tent at a substantial discount, it can be excellent value. For someone comparing it with a modern premium two-person ultralight shelter, the limitations become much more obvious.
What Is the Mountain Warehouse Backpacker 3?
The Mountain Warehouse Backpacker 3 is a three-person backpacking and trekking tent aimed primarily at affordability and portability.
The concept is straightforward: give hikers a shelter that is considerably more pack-friendly than a conventional family tent, while keeping the price accessible.
Its approximately 2.7 kg weight is important here.
For a three-person tent, that works out to roughly:
900 g per person when shared by three campers.
For two people:
1.35 kg per person.
That is a useful way to evaluate tent weight.
A 2.7 kg shelter might sound heavy when compared with high-end ultralight tents, but if three people divide the tent body, poles and rain protection between them, the individual load becomes much more reasonable.
This is one of the most important backpacking principles:
Never judge a multi-person tent solely by its total weight. Judge the weight per sleeper and consider how the components can be divided.
That said, solo backpackers will feel the full 2.7 kg much more than a group of three.
1. It Offers a Lot of Interior Space for the Money
One of the Backpacker 3's biggest advantages is its floor area.
The published dimensions are approximately 300 × 240 cm, which is a substantial footprint for a budget backpacking shelter.
There is a catch, however: tent dimensions don't automatically translate into usable living space.
The floor may be large, but the walls and roof geometry determine how much of that area you can actually use comfortably.
Still, the Backpacker 3 feels considerably more spacious than many compact two-person trekking tents.
For two people, this can be particularly attractive.
You have more room to:
Spread out sleeping pads
Store backpacks
Change clothing
Organize equipment
Keep essential items within reach
Sit up and move around
Wait out a short rain shower
This is a good example of why livability deserves as much attention as weight.
A tent that saves 500 grams but forces two people to spend a wet afternoon shoulder-to-shoulder may not actually be the better shelter for every trip.
2. The 2.7 kg Weight Is Reasonable for Budget Backpacking
Let's put the weight into perspective.
A 2.7 kg tent isn't ultralight.
Modern premium backpacking tents can be dramatically lighter, particularly two-person models using advanced fabrics and minimalist pole structures.
But premium ultralight construction often comes with a significant price increase.
The Backpacker 3 therefore occupies an interesting middle ground:
Affordable + spacious + reasonably portable
rather than:
Extremely light + extremely compact + extremely expensive.
For weekend trips where you're hiking 5–15 miles per day rather than attempting a long-distance fastpacking challenge, 2.7 kg may be perfectly manageable.
For example, suppose two hikers split the shelter:
Camper A: tent body + stakes
Camper B: poles + fly + accessories
A 2.7 kg tent becomes approximately 1.35 kg per person before accounting for how you distribute individual components.
That's much easier to justify.
The Backpacker 3 uses 7001-series aluminum poles.
This is a positive feature.
Aluminum poles generally provide a useful combination of:
Low weight
Good strength-to-weight ratio
Flexibility
Packability
Repairability compared with some more specialized pole systems
For budget equipment, pole material matters.
A tent can have excellent fabric and still perform poorly if its pole structure is fragile or poorly designed.
The Backpacker 3 isn't an expedition shelter, but aluminum poles make more sense for backpacking than very basic fiberglass pole systems commonly found on inexpensive recreational tents.
The tent uses taped seams, which is another feature worth paying attention to.
Why?
Because stitching creates tiny holes in waterproof fabric.
Even if the fabric itself is waterproof, water can potentially penetrate through the needle holes along a seam.
Seam taping covers that vulnerable area.
This is a basic but important piece of tent engineering.
A useful waterproofing lesson
When evaluating a tent, don't look only at the hydrostatic-head number.
Also ask:
Are the seams taped?
Is the floor adequately protected?
Does the rainfly cover the sleeping area?
Are doors protected?
Can water run directly toward the entrance?
Are there vulnerable points around pole attachments?
How well does the shelter maintain tension during rain?
Waterproofing is a system, not a single number.
The Backpacker 3 is generally listed with a 2,000 mm hydrostatic-head rating.
This figure deserves some explanation.
What Does 2,000 mm Hydrostatic Head Mean?
Hydrostatic head is a laboratory measurement of water pressure a fabric can withstand before water penetrates.
A rating of 2,000 mm means the fabric can theoretically withstand the pressure produced by a 2-meter column of water under the specified test conditions.
However, that doesn't mean:
"This tent can withstand exactly 2 meters of rain."
Rain doesn't behave like a stationary column of water.
Real-world waterproofing is influenced by:
Wind
Rain intensity
Fabric aging
Abrasion
Seam construction
Ground pressure
Hydrostatic pressure from knees or gear
Pitch tension
Water pooling
Manufacturing variation
For normal summer backpacking, 2,000 mm can be serviceable, particularly when the shelter is pitched correctly.
But I wouldn't treat the Backpacker 3 as a serious storm shelter simply because it has a 2,000 mm rating.
Why Ground Pressure Matters
Here's an often-overlooked camping skill.
Imagine kneeling on the tent floor.
Your body weight is concentrated into a relatively small area.
That creates much greater pressure on the fabric than falling rain.
The same principle applies to:
Knees
Elbows
Sleeping pads
Backpack corners
Wet equipment
Sharp rocks underneath the tent
This is why a fabric's hydrostatic-head rating doesn't tell the entire story.
Always use a suitable groundsheet or footprint when the terrain is abrasive, rocky or wet, and avoid pitching directly on sharp objects.
For light to moderate rain and normal summer conditions, it can be a practical shelter.
But I would be more cautious in prolonged heavy rain.
That's where the distinction between budget backpacking and premium backcountry equipment becomes important.
A tent's performance isn't determined only by whether water initially enters.
You also need to consider:
Condensation
Wind-driven rain
Seam durability
Fabric aging
Groundwater
Splashback
Door design
Ventilation
Pitch stability
A tent that keeps you dry for a two-hour summer shower isn't necessarily the same thing as a tent you'd confidently choose for a multi-day mountain trip with a poor weather forecast.
One of the most important things to understand about tents is that water inside the tent doesn't always come from outside.
Sometimes it comes from you.
An adult can release a surprisingly significant amount of moisture through breathing and perspiration during a night.
Imagine two people sleeping inside a small shelter.
Every breath adds warm, moist air.
When that moisture reaches a colder tent surface, it can condense into droplets.
This is why a perfectly waterproof tent can still have a wet interior in the morning.
Common causes of condensation
Cold nighttime temperatures
High humidity
Wet clothing inside the tent
Wet sleeping bags
Two or three people sleeping in a small space
Poor airflow
Pitching near water
Sleeping with all ventilation closed
How to reduce condensation
1. Ventilate whenever weather permits.
Don't completely seal yourself inside the tent unless conditions require it.
2. Keep wet gear outside the sleeping area when practical.
A soaked jacket can introduce a surprising amount of moisture.
3. Avoid pitching directly beside lakes, streams or marshy ground.
These areas can have higher local humidity.
4. Don't touch the inner walls with your sleeping bag.
Condensation can transfer directly into insulation.
5. Use cross-ventilation.
Air movement is one of the simplest ways to control moisture.
This is one area where experienced campers often have a noticeably better experience than beginners—not because their tent is necessarily better, but because they understand how to manage moisture.
Technically, yes.
Practically?
I'd call it a comfortable two-person tent and a more compact three-person tent.
This is not unusual.
Tent capacity labels generally describe how many sleeping spaces can physically fit, not how comfortable those people will be with backpacks, clothing and equipment.
For three adults, especially three adults with full-size sleeping pads and backpacks, interior organization becomes more challenging.
My recommendation
1 person: Very comfortable.
2 people: Excellent use case.
3 people: Suitable if everyone is willing to pack efficiently.
For two people, the extra floor area can become a major advantage.
You don't need to sacrifice the entire sleeping area to backpacks and clothing.
This is where the decision becomes interesting.
Suppose you are comparing the Backpacker 3 with a premium 2P backpacking shelter.
The premium tent may offer:
Lower weight
Smaller packed volume
Better fabrics
More sophisticated ventilation
Lower trail weight
More refined pole architecture
Better long-term durability
Larger or better-designed vestibules
But it will probably cost substantially more.
Meanwhile, the Backpacker 3 offers:
More floor area
Three-person capacity
Relatively straightforward construction
Aluminum poles
A lower purchase price
More forgiving space for beginners
So the choice isn't simply:
Which tent is better?
It's:
Which compromises make sense for your trips?
At around 2.7 kg, the Backpacker 3 isn't particularly light by modern backpacking standards.
This becomes more significant if you're hiking alone.
A solo backpacker carrying 2.7 kg of shelter is carrying a substantial percentage of their total sleep system.
For a pair, however, the calculation changes.
Weight-sharing example
| Situation | Approximate tent weight per person |
|---|---|
| One person | 2.7 kg |
| Two people | 1.35 kg |
| Three people | 0.9 kg |
This illustrates why group size matters enormously when evaluating tent weight.
If you're always backpacking alone, I wouldn't buy the Backpacker 3 simply because it is inexpensive.
If you're normally traveling with one or two partners, it becomes much more attractive.
The listed packed dimensions are approximately 51 × 20 × 20 cm.
That's not exceptionally tiny.
But it is manageable.
The important thing is to think about where the tent goes inside your backpack.
A 20 cm × 20 cm package can occupy a surprisingly large amount of useful space.
For backpacking, I prefer to avoid creating one oversized "brick" inside the pack.
A better packing strategy
If you're hiking with another person, separate the components:
Person A
Tent body
Stakes
Footprint
Person B
Poles
Rainfly
Repair kit
This can make both backpacks easier to organize.
Even better, store the poles vertically along the side of the backpack if the pack design allows it.
Backpacking efficiency isn't just about reducing grams. It's also about reducing awkward volume.
The general construction is relatively straightforward, which is good for beginners.
But there's an important distinction between:
Easy to pitch in a backyard
and
Easy to pitch at 10:30 p.m. in horizontal rain.
The latter is the real test.
Before taking any new tent into the backcountry, I strongly recommend doing a practice pitch at home.
Don't simply unfold it once.
Practice:
Identifying the front and rear.
Connecting every pole section.
Understanding how the poles attach.
Locating all guy points.
Adjusting tension.
Attaching the rain protection.
Packing it back into the bag.
Then practice again in low light.
This may sound excessive.
It's not.
A five-minute backyard practice can save you from a frustrating 30-minute setup on a windy mountainside.
A lightweight tent is not automatically a wind-resistant tent.
Wind performance depends on:
Pole geometry
Pole strength
Tent shape
Fabric tension
Guyline placement
Peg quality
Pitch orientation
Ground conditions
One of the most useful tent skills: pitch into the wind
Whenever possible, identify the predominant wind direction before pitching.
Orient the more aerodynamic end of the shelter toward the strongest wind rather than presenting the broadest wall directly into it.
Then:
Stake the corners securely.
Tension the shelter evenly.
Use guy lines when conditions warrant.
Check every attachment point.
Avoid exposed ridgelines if severe weather is forecast.
A $500 tent can fail in bad conditions if poorly pitched.
A budget tent can perform surprisingly well when carefully pitched within its intended conditions.
This is where I'd lower expectations.
The Backpacker 3 is built around affordability.
That means I wouldn't expect the same long-term material durability as a premium tent costing several times more.
Potential wear points on budget backpacking tents include:
Thin fabrics
Zippers
Seam tape
Pole joints
Pole sleeves
Webbing attachment points
Floor abrasion
Stuff sack compression
This doesn't mean the tent is fragile.
It means maintenance matters more.
To extend its lifespan
After every wet trip:
1. Dry the tent completely.
Never store a wet tent for days.
2. Shake out dirt and sand.
Tiny particles can act like abrasive material.
3. Don't drag the tent across the ground.
Lift it.
4. Store it loosely when possible.
Long-term compression isn't ideal for many tent materials.
5. Inspect the poles.
Check for cracks, bent sections and damaged shock cord.
6. Inspect seam tape.
Early deterioration is much easier to address than a major leak during a trip.
If you buy the Backpacker 3, I strongly recommend considering a footprint.
But there's a common mistake:
A footprint should not extend beyond the tent floor.
If it sticks out, rain can collect on the exposed footprint and run underneath your tent.
That can actually make water problems worse.
A footprint should generally be:
Slightly smaller than the tent floor
Lightweight
Smooth enough not to damage the tent
Easy to fold
Properly positioned
You can also use a suitably sized lightweight groundsheet if you understand how to trim and position it correctly.
I would consider it a good choice for:
Beginner Backpackers
If you're buying your first backpacking tent and don't yet know whether you'll backpack five times or fifty times a year, spending a fortune immediately may not make sense.
Budget-Conscious Campers
This is arguably its strongest category.
The Backpacker 3 delivers useful functionality without entering premium pricing territory.
Couples
Two people can take advantage of the relatively generous interior.
Summer Trekkers
For fair-weather and moderate conditions, its compromises are easier to accept.
Festival and Travel Camping
The portability and relatively simple design make it useful beyond traditional backpacking.
Short Weekend Trips
For a one- or two-night trip, the balance of price, space and weight can be compelling.
I'd look elsewhere if you are:
An Ultralight Backpacker
If every gram matters, 2.7 kg will probably feel excessive.
A Solo Long-Distance Hiker
Carrying the entire tent alone makes the weight less attractive.
A Four-Season Camper
This is not the tent I'd select for serious winter mountaineering or sustained snow loading.
A Frequent Expedition Camper
If you're spending dozens of nights outdoors every year, investing in higher-quality materials may provide better long-term value.
Someone Expecting Luxury
The Backpacker 3 is not a tiny outdoor apartment.
There's a difference between spacious for a backpacking tent and spacious in absolute terms.
Pros
Affordable compared with many dedicated backpacking tents
Approximately 2.7 kg, which is reasonable when shared
Generous floor area
Three-person capacity
Aluminum poles
Taped seams
Compact enough for backpacking
Useful for beginners
Particularly attractive for two-person use
Good value when heavily discounted
Cons
Heavy compared with modern ultralight shelters
Not ideal for solo backpacking
2,000 mm waterproofing is adequate rather than exceptional
Limited suitability for severe weather
Budget-oriented materials
Interior capacity becomes tight with three adults plus full gear
Packed volume isn't especially small
Ventilation requires careful management to control condensation
The word ultralight is frequently misunderstood.
There is no magic number at which a tent suddenly becomes ultralight for every user.
Consider three variables:
Total weight + capacity + livability
A 1.2 kg two-person tent may be significantly lighter than the Backpacker 3, but that doesn't automatically mean it offers a better experience.
Perhaps its interior is narrower.
Perhaps it has a smaller vestibule.
Perhaps it uses a thinner fabric.
Perhaps it costs three or four times as much.
Perhaps it requires trekking poles.
The real question is:
How much functionality are you receiving for every gram you carry?
That's a much more useful way to think about backpacking gear.
Here's a useful calculation you can use when comparing tents:
Shared shelter weight = Total tent weight ÷ Number of users
But don't stop there.
Also calculate:
Shelter weight per square meter of floor area
and consider:
Shelter weight per usable sleeping position
These calculations help reveal why some "light" tents aren't necessarily more efficient.
A tent might save 500 grams while losing substantial interior space.
Another might weigh slightly more but give two people dramatically more usable living area.
Weight efficiency is more meaningful than weight alone.
If I were redesigning the Backpacker 3 for serious modern backpacking, I would focus on five areas.
1. Reduce Pack Weight
The first target would be reducing the total shelter system while maintaining structural integrity.
2. Improve Ventilation
Better adjustable ventilation would help reduce condensation, particularly when two or three people are sleeping inside.
3. Improve Weather Protection
A more sophisticated rainfly and better storm management would expand the range of conditions in which I'd recommend it.
4. Increase Storage Efficiency
A better vestibule can sometimes improve livability more efficiently than simply adding floor area.
5. Improve Long-Term Repairability
Replaceable poles, standardized hardware and easily repairable components can make a tent much more sustainable over years of use.
If you already own one, these tips can significantly improve your experience.
1. Practice Before Your First Trip
Never make your first setup a nighttime setup.
2. Use a Proper Pitch
A loose pitch can cause wrinkles, poor drainage and unnecessary wind movement.
3. Ventilate Early
Don't wait until condensation has already formed.
4. Keep Wet Clothing Away From Sleeping Gear
Your sleeping bag works best when it stays dry.
5. Carry Spare Stakes
Budget tent kits often provide only the minimum number needed for a basic pitch.
A few lightweight spares are cheap insurance.
6. Bring a Small Repair Kit
Consider carrying:
Repair tape
Pole splint
Spare cord
Small patches
A few spare stakes
A tiny repair kit can turn a potentially trip-ending problem into a ten-minute fix.
7. Dry It Completely
This is perhaps the easiest way to extend the life of the tent.
Yes—if you buy it for the right reasons.
The Mountain Warehouse Backpacker 3 isn't competing directly with premium ultralight shelters.
Its real strength is the combination of:
Price + Space + Reasonable Weight + Simplicity
For a couple on weekend backpacking trips, it can make considerable sense.
For three people, it provides useful sleeping capacity at a relatively accessible weight.
For a beginner, it provides a practical way to enter backpacking without immediately investing in an expensive shelter system.
But if you're planning serious long-distance hiking, frequent alpine trips, harsh weather camping, or ultralight backpacking, I'd recommend looking beyond it.
The Mountain Warehouse Backpacker 3 is a budget backpacking tent rather than a premium ultralight tent—and that's perfectly fine.
Its approximately 2.7 kg weight, generous floor area, aluminum poles and 2,000 mm waterproof rating make it a sensible option for the right conditions.
Its biggest advantage isn't that it is exceptionally light.
It isn't.
Its biggest advantage is that it gives you a lot of shelter for relatively little money.
For two campers, the equation becomes particularly attractive because the 2.7 kg weight can be divided between users.
For three campers, it offers a useful compromise between individual weight and interior space.
The compromises become more apparent when the weather gets serious or when you start comparing it with expensive ultralight shelters.
So, is the Mountain Warehouse Backpacker 3 worth it?
My answer:
Worth it for budget backpackers, beginners, couples, summer trekking and occasional camping: YES.
Worth it for ultralight enthusiasts, severe-weather backpacking and frequent expedition use: probably not.
The most important lesson is not to buy a tent based on one specification.
A good shelter is a balance of weight, capacity, weather protection, ventilation, durability, setup, packed size and livability.
And that last factor is often overlooked.
Because a backpacking trip doesn't end when you reach camp.
That's when you actually start living in your tent.
Is the Mountain Warehouse Backpacker 3 good for backpacking?
Yes. Its design, packed size and approximately 2.7 kg weight make it suitable for backpacking and trekking, particularly for short trips and budget-conscious users.
Can three adults sleep in the Backpacker 3?
Yes, but three adults will have significantly less personal and gear space than two adults. For maximum comfort, I'd generally prefer using it with two people.
Is the Backpacker 3 waterproof?
It is designed for wet-weather protection and is listed with a 2,000 mm hydrostatic-head rating and taped seams. However, this should be regarded as suitable for moderate conditions rather than a guarantee of performance in prolonged severe storms.
How much does the Backpacker 3 weigh?
The listed packed weight is approximately 2.7 kg.
Is 2,000 mm hydrostatic head enough for camping?
For many normal three-season camping situations, 2,000 mm can be adequate. However, waterproof performance depends on much more than hydrostatic head, including seams, construction, pitch, ground conditions and fabric condition.
Is it good for winter camping?
I would not choose the Backpacker 3 for serious winter or mountaineering conditions. Winter shelters need to be designed around snow loading, stronger winds, colder temperatures and different ventilation requirements.
Is the Backpacker 3 good for two people?
Yes. This is arguably one of its best use cases. Two campers can share the shelter weight while benefiting from the relatively generous interior.
Is the Mountain Warehouse Backpacker 3 ultralight?
No. At approximately 2.7 kg, it is better described as a reasonably portable budget backpacking tent rather than an ultralight shelter.
What is the biggest problem with the Backpacker 3?
For most experienced backpackers, the main issue is weight relative to modern ultralight alternatives. For beginners, ventilation, condensation management and understanding the limits of its weather protection may be more important concerns.
The outdoor industry has spent years pushing the idea that a better backpacking tent is simply a lighter backpacking tent.
Weight absolutely matters.
Every gram you carry eventually becomes part of the physical cost of your journey.
But there is another side to the equation.
After walking for hours, you arrive at camp. You take off your pack. You need to change clothes, organize equipment, eat, wait out rain, dry your gear, sleep, wake up, and prepare for another day.
At that point, livability matters.
The best shelter isn't necessarily the one with the lowest number on a scale.
It's the one that creates the best balance between what you carry on the trail and how well you can live when you arrive.
That is a useful principle to remember when comparing any backpacking tent—not just the Mountain Warehouse Backpacker 3.
About HillZero
HillZero — Livable Backpacking Tents.
HillZero is a premium outdoor design brand focused on Livable Backpacking: finding a better balance between carrying less on the trail and living better once you arrive.
Its philosophy is simple: Carry Less. Live Better.
HillZero doesn't see backpacking as simply moving from one destination to another, and it doesn't see a tent as merely a place to sleep. A backpacking shelter is part of the complete experience of walking, arriving, resting, organizing gear, staying dry, cooking, observing nature and spending meaningful time outdoors.
That leads to a fundamental design question:
How can a backpacking tent be easier to carry, without making it harder to live in?
HillZero develops its tents around this idea, considering practical details such as space utilization, ventilation, entry and exit, movement, privacy and long-term comfort rather than pursuing the lowest possible weight at any cost.
Its first core product direction is Livable Backpacking Tents, beginning with the Scott 2P and a design philosophy built around a simple idea:
Light enough to carry. Livable enough to stay.
HillZero is not trying to make backpacking heavier in the name of comfort, nor lighter at the expense of the experience. It is rethinking what deserves to remain in a lightweight shelter—and what can be removed without making life at camp harder.
