The NEMO Losi 2P is an interesting tent to review because it represents a different era of backpacking-tent design.
Before the current generation of aggressively ultralight shelters became so dominant, designers were more willing to spend a few extra ounces—or even pounds—to create a tent that felt genuinely comfortable at camp. The Losi 2P is a good example of that philosophy.
It is a three-season, freestanding two-person tent with a relatively large interior, tall walls, two doors, two vestibules, and a distinctive multi-pole architecture. Depending on the exact production version, published specifications vary slightly, but the Losi 2P is generally around 4.9–5.9 pounds packaged, with approximately 31–33 square feet of floor area and an interior height approaching 46 inches.
That makes it noticeably heavier than many modern two-person backpacking tents.
But here's the question that matters:
What do you get for carrying that extra weight?
After years of testing tents in rain, wind, heat, cold, and extended camp situations, I think the Losi 2P is best understood not as an ultralight tent, but as a high-livability backpacking shelter.
It gives up some trail efficiency to create a much more comfortable environment once the day's hiking is finished.
This review examines the NEMO Losi 2P's weight, interior space, pole design, ventilation, weather resistance, durability, setup, packability, and real-world backpacking performance—and whether its comfort-oriented design still makes sense today.
NEMO Losi 2P at a Glance
Because the Losi 2P has existed in multiple production versions, specifications can differ slightly depending on the year and model generation. The following figures represent the commonly published specifications for the classic Losi 2P configuration.
| Specification | NEMO Losi 2P |
|---|---|
| Capacity | 2 people |
| Season Rating | 3-season |
| Minimum Weight | Approximately 4 lb 15 oz |
| Packaged Weight | Approximately 5 lb 9 oz |
| Floor Area | Approximately 31–33 sq. ft. |
| Floor Dimensions | Approximately 84 × 54 in. |
| Interior Height | Approximately 46 in. |
| Vestibule Area | Approximately 20 sq. ft. total |
| Doors | 2 |
| Vestibules | 2 |
| Structure | Freestanding |
| Pole Material | DAC aluminum |
| Canopy | Polyester/No-see-um mesh |
| Rainfly | Coated nylon ripstop |
| Floor | Coated polyester/nylon |
| Season | 3-season |
The numbers immediately tell us something important.
This is a large two-person tent.
Its approximately 46-inch peak height is especially notable.
Many backpacking tents are designed around a low center point where you can sit upright but don't have much additional room. The Losi takes a different approach, using multiple poles to push the walls outward and create more usable volume.
That decision adds weight and complexity.
It also makes the interior significantly more pleasant.
The Losi 2P doesn't follow the minimalist "one pole, thin fabric, tiny footprint" formula.
Instead, its design emphasizes:
High interior volume
Relatively vertical walls
Two independent entrances
Two vestibules
Freestanding construction
Substantial structural support
Large areas of mesh
Good sitting height
A comfortable rectangular floor
The result is a tent that feels surprisingly close to a small portable room compared with many lightweight two-person shelters.
That is the Losi's central attraction.
Let's get the obvious criticism out of the way.
The Losi 2P is heavy.
At roughly five pounds or more depending on the version and what is included in the weight measurement, it is substantially heavier than many contemporary ultralight two-person tents.
For one person, that's a serious burden.
For two people sharing the shelter, the calculation becomes more reasonable.
If you divide approximately 5 pounds between two hikers:
5 lb ÷ 2 = 2.5 lb per person
That's still not ultralight, but it is much easier to justify when each person is carrying part of the shelter.
Why Is the Losi 2P So Heavy?
Weight doesn't simply disappear.
It generally comes from somewhere.
In the Losi's case, some of that weight comes from:
Multiple aluminum poles
Large interior dimensions
More substantial fabric
Two-door construction
Two vestibules
Large mesh panels
Structural components designed to increase usable volume
This is an important lesson when comparing tents.
If one shelter weighs 3 pounds and another weighs 5 pounds, the question shouldn't simply be:
"Which one is better?"
Instead ask:
"What did the manufacturer remove from the lighter tent, and what did the heavier tent preserve?"
Sometimes the answer is almost entirely fabric.
Sometimes it's interior volume.
Sometimes it's structural complexity.
In the Losi's case, a meaningful portion of the weight buys space and livability.
If weight is the Losi's biggest weakness, interior space is its greatest strength.
The floor is approximately 84 × 54 inches, depending on the specific version.
That gives two adults enough room for normal backpacking sleeping pads without creating an excessively narrow sleeping platform.
But the real advantage isn't just the floor.
It's the wall geometry.
Two tents can have the same floor area and feel completely different.
Consider a hypothetical 31-square-foot tent.
Tent A
Low peak
Aggressively sloping walls
Narrow shoulder area
Tent B
Tall center
More vertical sidewalls
Better pole-supported geometry
Even though both have roughly the same floor area, Tent B will feel significantly larger.
The Losi 2P belongs to the second category.
Its multi-pole structure pushes the upper walls outward, creating more usable space around your shoulders and head.
That's particularly valuable when:
Changing clothes
Sitting up
Organizing gear
Reading
Eating
Waiting out rain
Sharing the tent with another person
A peak height around 46 inches is generous for a backpacking tent.
You still won't stand inside.
But standing isn't the relevant benchmark.
The relevant benchmark is:
Can two people sit comfortably without constantly touching the ceiling?
The Losi performs very well here.
The extra height also creates more psychological space.
A low shelter can feel restrictive even when the floor area is adequate.
A taller shelter tends to feel more open.
This is one reason experienced campers sometimes become willing to carry more weight after years of using ultralight equipment.
Livability becomes more noticeable the longer you spend inside the shelter.
Yes.
And unlike some aggressively tapered two-person shelters, it actually feels designed around two adults.
For two backpackers, there's enough room to:
Sleep without constantly touching
Change clothing
Store small personal items
Sit upright
Move around without immediately disturbing your partner
But there is an important distinction.
The Losi 2P is comfortable for two, not luxurious for two in the way a large three-person tent would be.
If you're traveling with a large dog or substantial camera/climbing equipment, a three-person shelter may make more sense.
The Losi 2P's dual-entry layout is one of its most practical features.
Each occupant gets a dedicated entrance.
That means you don't need to:
Climb over your partner
Crawl across sleeping bags
Move gear at night
Wake someone when leaving the tent
This is especially useful for couples with different schedules.
One person can get up before sunrise while the other continues sleeping.
Vestibule Space Is More Important Than It Looks
The Losi provides approximately 20 square feet of total vestibule space, depending on the configuration.
That creates separate outdoor storage zones for each camper.
You can keep:
Backpack
Hiking shoes
Trekking poles
Rain jacket
Wet clothing
Cooking equipment
Dirty gear
outside the inner tent.
This creates a useful organizational principle:
Clean sleeping space inside.
Dirty and wet equipment outside.
The separation becomes particularly valuable during multi-day trips.
The Losi's pole system is one of its most distinctive features.
Rather than relying on a simple single-pole structure, the tent uses multiple DAC aluminum poles, with the geometry designed to increase interior volume.
This is clever engineering.
But it also introduces a trade-off:
More poles generally mean more setup steps, more components, and more weight.
Is the Losi 2P Hard to Set Up?
Not exactly.
But it isn't as immediately intuitive as some modern single-hub backpacking tents.
The first few setups may require more attention to:
Pole orientation
Pole intersections
Attachment points
Rainfly positioning
Correct tension
After you've practiced, the process becomes much easier.
My recommendation
Set the Losi up at home at least twice before your first backcountry trip.
Don't wait until you're exhausted, it's raining, and daylight is disappearing.
This is a universal backpacking principle:
Practice complicated gear when you're comfortable, not when you're desperate.
The Losi 2P's freestanding architecture makes campsite positioning easier.
You can assemble the main structure and move it slightly before fully staking it down.
That is particularly useful when:
The ground is uneven
You need to optimize the door orientation
The wind direction changes
You want the vestibules positioned away from runoff
You discover a rock beneath one corner
However:
Freestanding does not mean you should skip staking.
In windy conditions, proper anchoring is essential.
The Losi 2P is designed as a three-season double-wall tent.
Its weather-protection system consists of:
Inner canopy
Full rainfly
Waterproof floor
Coated fabrics
Aluminum pole structure
Stake and guy-out points
The specific waterproof ratings vary somewhat between production generations, with commonly listed figures around 1,200–1,500 mm for the fly and approximately 1,500 mm for the floor on classic versions.
These numbers should be interpreted carefully.
Hydrostatic head is a measurement of the water pressure a fabric can resist under standardized test conditions.
It does not directly mean:
"This tent can handle X millimeters of rainfall."
Real-world performance depends on many additional variables.
For example:
Seam sealing
Coating condition
Fabric aging
Ground pressure
Abrasion
Rain intensity
Wind
Pitch quality
Water pooling
A tent with a high laboratory rating can still leak if a seam fails or the rainfly is incorrectly pitched.
Conversely, a properly maintained tent with a moderate rating can perform very well in ordinary three-season rain.
When evaluating a tent during wet-weather camping, I pay attention to several things.
1. Does the rainfly maintain separation from the inner tent?
If wet fly fabric touches the inner canopy, water can sometimes transfer through contact.
2. Does water drain away naturally?
A good campsite is still essential.
3. Do the doors and zippers shed water effectively?
Entry points are common weak areas.
4. Does the floor remain dry under pressure?
Sleeping pads and knees create localized pressure.
5. Does the tent remain ventilated?
A completely sealed tent may stay dry from rain but become wet from condensation.
That final point is extremely important.
Many campers think waterproofing is simply about stopping rain.
In reality, internal condensation can be a bigger source of moisture than external rain.
Two sleeping people continuously add water vapor to the tent.
That moisture eventually reaches a cold surface and condenses.
A simple example:
If warm, humid air inside the tent contacts a rainfly that has cooled significantly overnight, the air can reach its dew point.
The result is water droplets.
This isn't necessarily a tent defect.
It's thermodynamics.
The Losi's large mesh canopy is a major advantage for warm-weather ventilation.
The mesh allows air movement while keeping insects outside.
That combination works particularly well during:
Summer camping
Humid evenings
Low-elevation forest trips
Dry desert nights
Stargazing
On dry nights, you can also use the tent with greater portions of the fly opened or removed, depending on the configuration and conditions.
How to Reduce Condensation in Any Double-Wall Tent
Use this simple checklist:
Open vents whenever weather permits.
Don't cover mesh areas with clothing or gear.
Avoid pitching immediately beside ponds or streams when possible.
Don't bring unnecessary wet gear into the sleeping compartment.
Keep the rainfly properly tensioned.
Allow airflow through opposing openings.
Dry the tent after the trip.
One of the biggest mistakes beginners make is closing every vent because the night feels cold.
That can actually make the inside wetter.
Ventilation is not just about staying cool. It's also about moisture management.
The Losi 2P performs particularly well in warm conditions because of its substantial mesh area.
The tall interior also creates a greater volume of air above the sleepers.
That can make the tent feel less claustrophobic on warm nights.
The two-door configuration provides another useful advantage.
If wind direction cooperates, opening opposing doors can encourage cross-ventilation.
Just remember to secure the tent appropriately if wind picks up.
The Losi 2P can work well for cool three-season conditions, but it is not a dedicated four-season tent.
That distinction matters.
A tent may remain comfortable at temperatures around freezing without being engineered for winter storms.
Winter introduces different structural and environmental problems:
Snow loading
Spindrift
Strong gusts
Frozen zippers
Longer nights
Greater wind exposure
If your trip involves sustained snow camping or alpine winter conditions, choose a shelter specifically designed for those environments.
The multi-pole design gives the Losi a solid structural framework.
Its aluminum poles are stronger and more reliable than many basic fiberglass systems found in inexpensive camping tents.
But no three-season backpacking tent should be treated as indestructible.
In strong weather:
Stake every corner
Use guy-out points
Keep the fly tensioned
Orient the narrowest practical profile into the prevailing wind
Check pole seating
Inspect the tent after major gusts
A tent's performance depends on both engineering and setup technique.
The Losi isn't built around the thinnest possible fabrics.
Depending on the generation, classic versions use materials in the neighborhood of 20D fly/canopy fabrics and 40D–68D-class floor materials.
That places it closer to traditional lightweight backpacking construction than today's extreme ultralight shelters.
This has practical advantages.
A somewhat more substantial floor gives you more tolerance for ordinary campsite imperfections.
But remember:
No tent floor is puncture-proof.
Avoid pitching directly on:
Sharp granite
Broken branches
Thorny vegetation
Exposed roots
Gravel with sharp edges
A footprint can help, but careful campsite selection remains your first defense.
It's tempting to judge a tent's durability solely by denier.
That's a mistake.
Durability comes from:
Fabric + stitching + pole structure + zippers + coatings + seams + handling
A 70D floor can be damaged if dragged across a sharp rock.
A lightweight floor can last years if treated carefully.
Likewise, poles are more likely to fail when they're assembled incorrectly or bent against excessive resistance.
If you're buying or already own an older Losi, maintenance becomes particularly important.
Inspect the rainfly
Look for:
Flaking coating
Sticky areas
Delamination
Pinholes
Brittle fabric
Inspect the floor
Check for:
Abrasion
Small punctures
Coating deterioration
Seam separation
Inspect the poles
Look for:
Bent sections
Cracks
Damaged ferrules
Weak shock cord
Inspect zippers
Make sure they move smoothly and don't show excessive tooth damage.
Older tents can remain highly functional, but age-related coating degradation is a real concern.
A tent can look almost new and still have degraded waterproofing.
Synthetic tent fabrics are often coated to create water resistance.
Over years of:
UV exposure
Folding
Heat
Moisture
Abrasion
Chemical contamination
those coatings can deteriorate.
If you're purchasing a used Losi 2P, don't judge its condition only from photographs.
Ask about:
storage conditions, frequency of use, and whether it was stored completely dry.
A lightly used tent stored damp can be in worse condition than a heavily used tent that was properly maintained.
The Losi's packed size is relatively manageable for a tent of its interior volume, but it is still considerably bulkier than many modern ultralight shelters.
This is the natural consequence of its design.
You're carrying:
Multiple poles
Larger fabric panels
A larger floor
Two vestibules
Additional structural components
For weekend trips, that isn't necessarily a problem.
For long-distance hiking, it becomes more significant.
For two hikers, don't automatically put the complete tent in one pack.
A better strategy is to distribute the components.
Hiker A
Tent body
Rainfly
Hiker B
Poles
Stakes
Footprint
Guylines
The exact division isn't important.
Balanced pack weight is.
Try to keep the heavier components close to your back and around the natural center of your pack.
This is where the tent makes a lot of sense.
Suppose you're hiking:
8–12 miles per day
and staying:
2–3 nights
The extra tent weight may be relatively easy to tolerate.
Once you're at camp, the benefits become obvious.
You have:
Room to sit
Room to move
Two entrances
Separate gear storage
Excellent visibility
Plenty of ventilation
The tent becomes part of your camp rather than merely somewhere to sleep.
This is a more complicated decision.
If you're carrying a shelter for:
1,000–2,000+ miles
then even an extra 1–2 pounds can represent a substantial cumulative load.
Suppose a tent is 1.5 pounds heavier.
Over a 2,000-mile hike, the pack isn't literally carrying that weight for every mile in a perfectly additive mechanical sense, but the hiker experiences that additional load throughout the journey.
This is why thru-hikers often prioritize:
Lower base weight
Smaller packed volume
Fast setup
Efficient shelter design
The Losi's comfort advantages become less valuable when your primary goal is maximizing daily mileage.
This is arguably the Losi's sweet spot.
If you hike several miles into a destination and stay for multiple nights, the value of interior space rises sharply.
Imagine reaching camp at 3 p.m. and knowing you don't need to pack the tent again until Thursday.
Now the tent's weight matters less than:
Sitting comfort
Storage
Ventilation
Protection
Organization
Space for changing clothes
Shelter during storms
This is where the Losi makes the strongest philosophical argument.
There is a useful way to think about backpacking shelters:
Category 1: Carry-first
Designed primarily to minimize what you carry.
Category 2: Balance-first
Attempts to balance weight and comfort.
Category 3: Livability-first
Accepts additional weight to create a better environment at camp.
The Losi 2P is much closer to Category 3 than today's ultralight tents.
And that isn't necessarily outdated thinking.
It's simply a different set of priorities.
| Feature | NEMO Losi 2P | Modern Ultralight 2P |
|---|---|---|
| Weight | Higher | Much lower |
| Floor Area | Generous | Usually moderate |
| Interior Height | Excellent | Moderate to good |
| Wall Steepness | Very good | Varies |
| Doors | 2 | Usually 2 |
| Vestibules | 2 | Usually 2 |
| Setup | Moderate | Often simpler |
| Durability | Good | Highly model-dependent |
| Packability | Moderate | Excellent |
| Long-Distance Hiking | Less ideal | Better suited |
| Basecamp Use | Excellent | Varies |
| Interior Livability | Excellent | Varies |
The important point is that weight and livability are often competing design variables.
Saving weight usually means removing something.
The skill is deciding whether the thing being removed matters to you.
The Losi 2P is particularly appealing to:
Couples Who Value Space
Two adults can comfortably share the shelter without constantly competing for elbow room.
Weekend Backpackers
The additional weight is easier to accept on shorter trips.
Basecamp Campers
The Losi becomes much more attractive when you're staying in one place for several nights.
Campers Who Spend Time Inside Their Tent
If rain frequently keeps you indoors, additional space has real value.
Comfort-Oriented Backpackers
If you're willing to carry extra weight to improve the camp experience, the Losi makes sense.
Ultralight Backpackers
There are substantially lighter shelters available.
Thru-Hikers
For long-distance mileage, the Losi's weight becomes difficult to justify.
Solo Backpackers
Carrying a large two-person shelter alone defeats much of the efficiency advantage of backpacking.
Winter Mountaineers
The Losi is a three-season design, not a dedicated snow or alpine shelter.
1. Practice the pole system before your trip
The multi-pole architecture isn't difficult, but familiarity makes setup much faster.
2. Pitch with the doors in mind
Think about wind direction, sunrise, and where you want to access your gear.
3. Use both vestibules
Give each person a designated storage area.
4. Keep wet gear outside
Your vestibule is an excellent moisture-management zone.
5. Vent early
Don't wait for condensation to build before opening vents.
6. Use a footprint when appropriate
Especially on rough ground, a properly fitted footprint can reduce floor abrasion.
7. Never store the tent damp
Dry it completely before long-term storage.
8. Inspect older coatings
If you're using a vintage Losi, check the fly and floor for coating degradation.
9. Stake the tent in wind
Freestanding doesn't mean wind-proof.
10. Choose the campsite carefully
A good site is still the foundation of weather protection.
Before you unpack the Losi, ask yourself these five questions:
1. Where will water go?
If the answer is toward your tent, move.
2. Where is the wind coming from?
Orient the shelter accordingly.
3. Are there dead branches overhead?
If yes, choose another location.
4. Is the ground comfortable enough to sleep on?
You can carry an excellent tent and still have a terrible night because of rocks.
5. Can the doors open freely?
Avoid placing the entrance directly against obstacles or dense vegetation.
Five minutes of planning can prevent hours of discomfort.
This is perhaps the most important lesson from using tents over many years.
Backpacking is usually discussed in terms of:
miles, elevation, ounces, calories, and speed.
But the day doesn't end when you reach camp.
Suppose two hikers walk 10 miles and arrive at 4 p.m.
It begins raining.
They cook dinner.
The temperature falls.
They need to organize tomorrow's gear.
They want to read.
They may spend four or five hours inside the shelter before sleeping.
At that point, the tent has become a living space.
The extra height and width of the Losi suddenly matter.
This is why experienced backpackers sometimes choose equipment that looks "too heavy" on a spreadsheet.
They aren't necessarily carrying inefficient gear.
They may simply be optimizing for a different part of the experience.

The weight score deserves context.
A six-out-of-ten doesn't mean the Losi is poorly designed.
It means that compared with modern ultralight tents, its weight is undeniably substantial.
Its excellent livability is precisely where that weight goes.
The NEMO Losi 2P is not the tent I'd choose if my only goal were to minimize pack weight.
There are simply too many lighter options available.
But if the goal is to create a comfortable two-person basecamp that can still be carried into the backcountry, the Losi remains an interesting design.
Its generous interior, approximately 46-inch peak height, dual doors, dual vestibules, large mesh areas, and multi-pole geometry give it a distinctly livable character.
Its weaknesses are equally clear:
It is heavy.
It packs larger than modern ultralight shelters.
Its setup requires more familiarity.
Older examples need careful inspection for fabric and coating degradation.
But those compromises buy something that is increasingly valuable in modern backpacking:
space.
And space isn't simply a luxury.
It can improve:
Sleep quality
Organization
Weather-day comfort
Drying strategies
Clothing changes
Personal privacy
Time spent relaxing at camp
The Losi 2P therefore makes the most sense for backpackers who don't measure success solely by how few ounces they carry.
If you're hiking moderate distances, sharing the tent with a partner, spending multiple nights at camp, or simply prefer a shelter that feels like a place to live rather than just sleep, the Losi's design philosophy remains compelling.
The central lesson is simple:
The lightest tent isn't automatically the best tent. The best tent is the one whose weight, space, protection, and livability match the way you actually spend time outdoors.
And that is where the NEMO Losi 2P continues to make a strong argument.
About HillZero
HillZero is a premium outdoor design brand focused on Livable Backpacking Tents. Its philosophy is captured in four simple words: Carry Less. Live Better.
HillZero approaches backpacking from a broader perspective. A backpacking trip isn't only about moving from one point to another, and a tent isn't simply a lightweight container for sleeping. The experience also includes arriving, resting, organizing gear, staying dry, cooking, watching the landscape, and spending meaningful time in the places we travel to reach.
That thinking leads to one central design question:
“How can a backpacking tent be easier to carry, without making it harder to live in?”
HillZero's Livable Backpacking design approach looks at real-world use—including space utilization, ventilation, entry and exit, movement, privacy, gear organization, and extended stays—to determine which functions are worth preserving within a reasonable weight.
The goal isn't to create the absolute lightest tent.
It isn't to simply make a tent heavier in order to make it larger.
Instead, HillZero seeks a more thoughtful balance between carrying efficiency and the quality of life at camp.
Beginning with the Scott 2P, HillZero is developing a focused range of Livable Backpacking Tents built around this philosophy.
The mission is straightforward:
to make backpacking more livable.
Because going farther is only part of the experience.
Light enough to carry. Livable enough to stay.
