If you are searching for a backpacking shelter that feels fundamentally different from a conventional tent, the Kammok Mantis deserves a serious look.
Technically, the Mantis is not a traditional tent at all. It is an all-in-one hammock camping shelter that combines a hammock, integrated insect net, structural ridgeline, suspension system, rainfly, and stakes into one relatively compact package.
That distinction matters.
For the right camper, the Mantis can provide a remarkably comfortable sleeping platform while keeping you off wet, rocky, muddy, or uneven ground. For someone who regularly camps in treeless environments, however, the same design can become a major limitation.
So, is the Kammok Mantis worth it?
After looking at its weight, suspension system, sleeping comfort, weather protection, ventilation, insulation requirements, campsite selection, durability, and overall versatility, my answer is:
Yes—but only if your camping style is compatible with hammock camping.
The Mantis is one of the more thoughtfully integrated hammock shelter systems available. Its biggest strength is not simply weight or convenience. It is the way the components work together to create a complete suspended sleeping environment.
Its biggest weakness is equally obvious:
You need suitable trees.
Kammok Mantis at a Glance
The current standard Mantis is a one-person hammock shelter designed primarily for three-season camping and recreational use.
| Feature | Kammok Mantis |
|---|---|
| Shelter type | Hammock tent |
| Recommended sleeping capacity | 1 person |
| Hammock length | 120 inches |
| Hammock width | 56 inches |
| Ridgeline length | 115 inches |
| Rainfly | 15D ripstop nylon |
| Hammock fabric | 40D diamond ripstop nylon |
| Bug protection | Integrated removable mesh |
| Maximum weight capacity | 500 lb |
| Trail weight with rainfly | About 2 lb 11.5 oz |
| Total packed weight | About 3 lb 1 oz |
| Packed dimensions | About 10.5 × 6.1 × 6.1 inches |
| Season rating | 3-season |
| Suspension | Included tree straps |
| Structural ridgeline | Integrated |
| Guy-out points | 8 |
| Recommended use | Hammock camping, backpacking, basecamp |
Kammok also makes the lighter Mantis UL, which uses lighter materials and brings the complete system down to roughly 2 pounds with the rainfly, while the full packed package is approximately 2 lb 4 oz.
That difference is important if you are comparing the standard Mantis with ultralight backpacking shelters.
The simplest way to understand the Mantis is to think of it as a hammock that has been engineered into a complete tent system.
Instead of sleeping on the ground, you are suspended between two suitable anchor points.
The system includes:
Hammock body
Integrated structural ridgeline
Removable bug net
Rainfly
Tree straps
Suspension hardware
Guy lines
Stakes
Storage sack
This creates a shelter that combines several pieces of conventional camping equipment into one system.
The standard Mantis uses a 40D diamond-ripstop nylon hammock body, while the rainfly uses lightweight 15D ripstop nylon with a waterproof coating.
The integrated mesh canopy provides protection from insects without requiring a separate inner tent.
That all-in-one approach is one of the Mantis's biggest selling points.
After years of camping with everything from traditional dome tents to minimalist shelters and hammocks, I think the Mantis is most interesting because of its system-level design.
Many hammock setups require you to buy and combine:
A hammock
Suspension straps
A bug net
A ridgeline
A tarp
Guy lines
Stakes
An insulation system
The Mantis brings most of these pieces together.
That is valuable for beginners.
You don't have to spend months learning which hammock suspension, tarp geometry, bug net, and ridgeline work together.
The Mantis essentially says:
Here is the system. Learn how to hang it correctly.
That is a very reasonable approach for someone entering hammock camping.
Kammok markets the Mantis as a fast setup system, and the basic concept is genuinely straightforward.
The suspension uses a knotless design, which is a major benefit for beginners.
A typical setup looks like this:
Find two suitable trees.
Position the trees at an appropriate distance.
Wrap the suspension straps around the trees.
Connect the hammock.
Adjust the suspension height.
Set the structural ridgeline.
Deploy the bug net.
Attach and tension the rainfly.
Stake out the fly and guy lines.
Check the final hang before getting inside.
The first few setups may take longer than expected.
After several practice sessions, however, the process becomes much more intuitive.
The important part: tree selection
The hardest part of hammock camping is often not the hammock.
It is finding appropriate anchor points.
You want trees that are:
Healthy
Strong
Large enough to support the system
Appropriately spaced
Free from dangerous dead branches
Located on suitable terrain
Never hang beneath obviously dead or unstable trees.
A comfortable hammock isn't much use if the tree above you becomes a hazard.
One of the most useful hammock camping skills is understanding suspension angle.
A commonly used starting point is approximately a 30-degree angle between the suspension strap and the ground.
This is not a magical number that works perfectly for every hammock, but it provides a useful reference.
Why does angle matter?
Because changing the angle dramatically changes the forces transferred into the anchor points.
A simplified physics model shows that as the suspension becomes increasingly horizontal, the horizontal component of force rises sharply.
For example, if the total load is approximately 200 pounds and the suspension angle is around 30 degrees from horizontal, each side can experience a tension component substantially greater than the simple 100-pound vertical load.
As the angle becomes shallower, that tension increases rapidly.
This is why "tighter is better" is a bad hammock-hanging philosophy.
Do not crank the hammock suspension as tight as possible.
A properly hung hammock should have a noticeable sag.
The integrated structural ridgeline is one of the Mantis's most useful design features.
It helps establish a consistent hammock shape.
Instead of relying entirely on your suspension angle to determine the final geometry, the ridgeline gives the hammock a repeatable reference point.
That means:
More predictable sag
More consistent sleeping position
Easier setup
Better bug-net geometry
More reliable headroom
For beginners, this is particularly useful.
A hammock can feel confusing if every setup produces a different shape.
The ridgeline reduces that variability.
If you have only slept in ground tents, the first night in a properly configured hammock can feel surprisingly different.
The ground no longer matters nearly as much.
You don't have to worry about:
Roots
Small rocks
Hard soil
Mud
Uneven terrain
Water pooling beneath your sleeping area
Instead, the hammock creates a suspended sleeping platform.
The Mantis is approximately 120 inches long and 56 inches wide, providing enough room for a diagonal sleeping position.
Why sleep diagonally?
A common beginner mistake is trying to lie perfectly parallel with the hammock.
Instead, a slight diagonal position can flatten the sleeping surface.
Your body essentially creates a longer, flatter sleeping area.
This can reduce the feeling of being tightly wrapped in the hammock fabric.
This is one area where you should pay attention to the numbers.
The Mantis hammock is about 10 feet long.
That is plenty for many campers, but hammock length becomes increasingly important as your height increases.
If you are under approximately 6 feet tall, the dimensions are generally quite accommodating.
Around 6 feet and above, individual body proportions and sleeping preferences become increasingly important.
If you are particularly tall, I strongly recommend trying the hammock before committing to it for a long-distance trip.
A useful rule
Do not evaluate a hammock by lying straight down the middle for 30 seconds.
Set it up properly.
Lie diagonally.
Relax your legs.
Shift your shoulders.
Try your normal sleeping position.
Then ask whether your head and feet have sufficient clearance.
The Mantis has a high stated weight capacity, but that does not mean it is designed for two people to sleep in comfortably.
There is an important distinction between:
Weight capacity and sleeping capacity.
The standard Mantis is recommended for one sleeping occupant.
The high load rating is primarily about structural capacity, not available sleeping space.
For couples, a dedicated two-person hammock system or traditional tent is usually a better solution.
A hammock has a natural advantage during rain:
You are not sitting directly on wet ground.
But that does not mean hammock camping is automatically better in bad weather.
The rainfly becomes extremely important.
The Mantis uses a 15D ripstop nylon rainfly with a waterproof PU/silicone treatment and DWR finish.
The fly provides substantial coverage around the hammock.
When properly tensioned, it protects the sleeping area from rain while allowing air to move around the shelter.
Yes, within the limits of a three-season hammock shelter.
The key phrase is properly pitched.
Rain protection depends on:
Fly orientation
Tension
Wind direction
Tree spacing
Guy-line placement
Rain intensity
Wind-driven precipitation
In a calm rainstorm, the Mantis can provide an excellent sheltered environment.
In severe wind, however, you should pay much more attention to how the tarp is oriented.
Bad-weather setup
When storms are approaching:
Position the ridgeline to reduce exposure to prevailing wind.
Pull the fly low.
Stake every available storm-relevant point.
Tighten guy lines evenly.
Avoid overly exposed campsites.
Keep the hammock away from branches that could fall.
Check that the fly does not contact the hammock body.
Maintain enough ventilation to limit condensation.
The final point matters more than many campers realize.
Condensation is not exclusively a tent problem.
You can experience condensation in a hammock shelter when warm, humid air meets colder surfaces.
Your breathing adds moisture to the shelter environment throughout the night.
The good news is that hammock systems are generally well ventilated.
You have air moving underneath you and around the sides of the shelter.
That can make the Mantis feel significantly less stuffy than a small enclosed ground tent.
However, when the rainfly is pulled very low during a storm, ventilation decreases.
Weather protection and ventilation are always a balancing act.
Mosquitoes are one of the main reasons hammock campers use integrated bug nets.
The Mantis incorporates a full no-see-um mesh canopy.
This protects you from:
Mosquitoes
Black flies
Gnats
Other small flying insects
The integrated mesh is also useful psychologically.
Once you zip yourself inside, you can relax without constantly checking your sleeping bag for insects.
For summer camping in mosquito-heavy environments, this feature can be worth far more than a few ounces of weight savings.
The Mantis also incorporates a design that allows you to open or roll back portions of the shelter for greater visibility when weather and insects permit.
This is one of those features that doesn't show up well on a specification sheet.
But camping is not only about surviving the night.
Sometimes you want to lie back and watch:
Stars
Clouds
Sunset
Tree canopies
Falling leaves
A meteor shower
A shelter that allows you to open the view without completely dismantling the system can make camp feel much more enjoyable.
This is the Mantis's defining limitation.
A conventional tent can be pitched almost anywhere.
A hammock cannot.
You need:
Two suitable anchor points.
That means the Mantis is poorly suited to:
High alpine environments
Desert landscapes
Treeless plains
Beaches without suitable trees
Above-treeline routes
Certain heavily regulated wilderness areas
Some high-elevation environments
If your favorite backpacking destinations are dominated by open terrain, a hammock should probably not be your primary shelter.
This is the single most important question to answer before buying.
| Feature | Kammok Mantis | Traditional Backpacking Tent |
|---|---|---|
| Requires trees | Yes | No |
| Uneven ground | Excellent | Moderate |
| Rocky ground | Excellent | Can be difficult |
| Wet ground | Excellent | Requires good site selection |
| Flat open terrain | Poor | Excellent |
| Bug protection | Excellent | Excellent |
| Sitting upright | Limited | Usually better |
| Sleeping comfort | Excellent for many users | Depends heavily on pad |
| Setup learning curve | Moderate | Usually low |
| Wind exposure | Site dependent | Site dependent |
| Under-body insulation | Required | Sleeping pad |
| Tarp management | Important | Rainfly management |
| Campsite flexibility | Limited | High |
This table explains why hammock camping creates such divided opinions.
It is not inherently better or worse.
It is better for certain environments and worse for others.
This is perhaps the most important concept for first-time hammock campers.
A hammock underneath you is not automatically warm.
In fact, many people discover the problem called cold butt syndrome on their first cool night.
Why?
Because your sleeping bag's insulation compresses underneath your body.
Compressed insulation loses much of its ability to trap warm air.
Meanwhile, cold air flows beneath the hammock.
The result can be a surprisingly cold back and lower body.
You generally need some form of under-body insulation.
That can be:
An underquilt
A specially designed hammock sleeping pad
A compatible insulated sleeping system
An underquilt hangs beneath the hammock and maintains loft without being compressed by your body.
This is one of the major advantages of an underquilt.
Think of your insulation as two separate systems:
Top insulation: sleeping bag or quilt
Bottom insulation: underquilt or hammock-compatible pad
Both matter.
A traditional sleeping bag is optimized for sleeping on the ground.
When you lie on it, the insulation underneath your body compresses.
The compressed insulation provides relatively little thermal resistance.
That's why the bottom of a sleeping bag isn't equivalent to the top.
In hammock camping, this effect becomes especially noticeable because cold air can move beneath the hammock.
A good hammock sleep system therefore treats under-body insulation as a separate engineering problem.
This is one of the most useful lessons for new hammock campers.
The standard Mantis has a trail weight of approximately 2 lb 11.5 oz with the rainfly.
The complete packed system is around 3 lb.
That is reasonable, but it is important to define what "lightweight" means.
Compared with:
Traditional car-camping tents → light
Standard backpacking tents → competitive
Modern ultralight tents → relatively heavy
Minimalist tarp systems → heavy
The Mantis UL is a different story.
Its rainfly-equipped trail weight is approximately 2 pounds, with the complete packed system around 2 lb 4 oz.
That makes the UL version much more attractive to serious backpackers.
| Feature | Mantis | Mantis UL |
|---|---|---|
| Hammock fabric | 40D | 20D |
| Max weight capacity | 500 lb | 300 lb |
| Trail weight with fly | ~2 lb 11.5 oz | ~2 lb |
| Total packed weight | ~3 lb | ~2 lb 4 oz |
| Intended user | Recreational/backpacking | Weight-conscious backpacker |
| Durability margin | Higher | Lower |
| Price | Lower | Higher |
| Ultralight suitability | Moderate | Better |
The standard Mantis is the more forgiving choice.
The Mantis UL makes more sense if pack weight is one of your highest priorities.
The standard Mantis uses a heavier 40D hammock fabric.
That gives it a meaningful advantage in durability and load capacity compared with the 20D Mantis UL.
This is an important trade-off.
A lighter fabric isn't automatically better.
For example:
20D → less weight, lower load capacity, greater need for careful handling
40D → more weight, greater robustness, higher load capacity
If you're an experienced ultralight backpacker who treats gear carefully, the UL can make sense.
If you're a beginner who wants a forgiving system, the standard Mantis is arguably easier to recommend.
One detail I particularly like about the Mantis concept is the built-in organization.
The system provides multiple loops and storage points that can be used for:
Headlamp
Water bottle
Phone
Glasses
Small electronics
Clothing
Personal items
That matters because hammock camping doesn't give you a floor where you can simply throw your gear.
Organization becomes part of the shelter design.
A small gear-management system can make a hammock feel significantly more livable.
For sleeping, yes.
For living, it depends on what you expect.
The hammock is not a tiny sleeping bag.
The diagonal sleeping position creates a surprisingly comfortable platform.
But you still cannot treat it like a large tent.
You won't have a conventional floor where you can:
Sit cross-legged
Sort your entire backpack
Change pants easily
Cook inside
Spread equipment everywhere
And you should never cook inside the hammock shelter.
Fuel-burning stoves produce carbon monoxide and create a serious fire risk.
Cooking should take place outside the sleeping shelter in an appropriate, well-ventilated area.
It can be used in cold conditions, but the hammock itself is not what determines your temperature rating.
Your insulation system does.
For colder trips, you need to consider:
Underquilt temperature rating
Top quilt or sleeping bag rating
Wind protection
Clothing
Ground or air temperature
Humidity
Your personal metabolism
A hammock can actually feel very comfortable in cold weather when properly insulated.
But an improperly insulated hammock can become unpleasantly cold very quickly.
The biggest beginner mistake
Bringing a high-quality sleeping bag while forgetting that your backside also needs insulation.
Wind affects hammock camping differently from ground tents.
You are elevated above the ground, so wind can move underneath you.
The rainfly provides protection, but site selection remains critical.
Avoid exposed ridgelines when strong winds are forecast.
Instead, look for:
Natural windbreaks
Dense but healthy forest
Slightly sheltered terrain
Strong mature trees
Locations away from dead branches
Do not choose a campsite solely because the trees are conveniently spaced.
Tree health comes first.
Hammock campers should also think about environmental impact.
Use tree-friendly suspension straps rather than narrow cords that can damage bark.
Follow local regulations and campsite restrictions.
Avoid hanging on:
Small saplings
Vulnerable trees
Trees with damaged bark
Protected vegetation
And remember that hammock camping is not automatically lower impact.
Your straps, tarp, foot traffic, and campsite selection still affect the environment.
Good outdoor ethics remain important regardless of shelter type.

The Mantis makes the most sense for:
Beginner hammock campers
The integrated design eliminates much of the equipment-selection headache.
Backpackers who hate rocky ground
If you frequently camp in forested areas where flat ground is scarce, the hammock can be a major comfort upgrade.
Summer campers
The airflow and bug protection are excellent combinations for warm-weather camping.
Campers who value comfort
The diagonal sleeping position can be extremely comfortable once you learn the correct setup.
Basecamp campers
If you establish a campsite and explore the surrounding area during the day, the Mantis is an excellent lounging and sleeping system.
Backpackers who enjoy modular gear
You can configure the system according to conditions rather than carrying one fixed shelter configuration.
I would look elsewhere if you frequently camp:
Above treeline
In deserts
On alpine routes
In open grasslands
On beaches
In areas with few suitable trees
In places where hammock camping is restricted
You should also reconsider it if your primary goal is the lowest possible base weight.
The Mantis UL is competitive, but a minimalist trekking-pole shelter can still offer a different weight-to-space relationship.
The most important difference isn't weight.
It's where you can camp.
A traditional tent asks:
"Is there a reasonably flat piece of ground?"
A hammock asks:
"Are there two strong, healthy trees at the right distance?"
That completely changes campsite selection.
If your routes naturally take you through mature forests, this may be a minor issue.
If your routes regularly cross open landscapes, it becomes a deal-breaker.
Use this checklist before hanging your hammock.
Step 1: Check the trees
Look for healthy, mature trees.
Inspect for:
Dead limbs
Cracks
Rot
Leaning trunks
Unstable roots
Signs of disease
Step 2: Check the spacing
The trees need to accommodate the hammock and suspension system without forcing extreme angles.
Step 3: Check the ground
Even though you are sleeping above it, the ground still matters.
You need space beneath the hammock for:
Your body
Gear
Underquilt
Rainwater runoff
Step 4: Look overhead
This is critical.
Avoid hanging beneath dead branches or unstable limbs.
Step 5: Check the weather
Wind direction can determine which orientation is most comfortable.
Step 6: Consider morning sunlight
A morning-sun campsite can be pleasant in cold weather but uncomfortable during summer heat.
Once you have practiced at home, use this sequence in the field:
Find two healthy trees.
Check the overhead canopy.
Inspect the ground and drainage.
Install the suspension straps.
Attach the hammock.
Adjust for appropriate sag.
Confirm the ridgeline position.
Install the bug net.
Attach the rainfly.
Stake and tension the fly.
Install your underquilt.
Test the entire system before bedtime.
That final test matters.
Don't discover at midnight that your underquilt has slipped away from your back.
This is one of the techniques that can make or break your hammock experience.
Lie slightly diagonally rather than directly along the centerline.
Your head and feet should move slightly toward opposite sides.
This spreads your body across the hammock fabric and creates a flatter sleeping position.
If you are experiencing:
Knee pressure
A tight feeling around your shoulders
Excessive curling
Difficulty finding a natural position
Your suspension geometry or sleeping position may need adjustment.
Don't immediately conclude that hammock camping isn't comfortable.
Correct setup is part of the equipment.
After considering the complete system, I would rate the standard Kammok Mantis as a very good hammock shelter for the right environment.

The Mantis is not the universal replacement for a backpacking tent.
It doesn't need to be.
Its real strength is creating a highly integrated, comfortable, elevated sleeping system that works exceptionally well in forested environments.
If you frequently camp among suitable trees and value comfort, airflow, bug protection, and modularity, the Mantis can be an excellent choice.
If you regularly hike above treeline or across treeless landscapes, it is probably the wrong primary shelter.
So, is the Kammok Mantis worth it?
For hammock campers, yes.
For someone looking for a conventional backpacking tent, no—because it solves a somewhat different problem.
The Mantis is best understood not as a lightweight tent, but as a complete hammock camping ecosystem.
Its integrated bug net, structural ridgeline, rainfly, suspension, and compact design remove much of the complexity traditionally associated with building a hammock system from separate components.
Its standard 40D construction also gives it a substantial durability advantage over the lighter Mantis UL, while the Mantis UL is the more logical choice for backpackers who prioritize weight.
The most important lesson is this:
Choose the Mantis because you want to sleep in a hammock—not simply because you want a lighter tent.
If your preferred trails run through forests with healthy trees, the Mantis can turn difficult ground conditions into a non-issue.
If your adventures take you across open alpine terrain, deserts, or treeless landscapes, a conventional backpacking tent remains the more versatile solution.
Ultimately, the best shelter isn't the one with the most impressive specification sheet.
It is the one that fits the terrain you hike, the weather you encounter, the way you sleep, and how you actually spend your nights outdoors.
Is the Kammok Mantis a tent or a hammock?
It is best described as an all-in-one hammock tent system. It combines a hammock with an integrated bug net and rainfly, creating a suspended shelter rather than a conventional ground tent.
How much does the Kammok Mantis weigh?
The standard Mantis weighs approximately 2 lb 11.5 oz with the rainfly and about 3 lb when packed as a complete system. The Mantis UL is lighter, with the rainfly-equipped system weighing around 2 pounds.
Can two people sleep in a Kammok Mantis?
The Mantis is designed for one sleeping occupant. Its weight capacity should not be confused with its recommended sleeping capacity.
Do I need an underquilt?
For cool-weather hammock camping, some form of under-body insulation is strongly recommended. An underquilt is often the most effective solution because it preserves insulation loft underneath the hammock.
Is the Kammok Mantis waterproof?
The hammock itself is not a waterproof sleeping chamber. The rainfly provides the primary weather protection. Proper pitching and tension are essential for effective rain protection.
Is the Mantis good for backpacking?
Yes, particularly for backpacking in forested environments where suitable trees are available. The standard Mantis is reasonably lightweight, while the Mantis UL is better suited to weight-conscious backpackers.
Can I use the Mantis in winter?
It can be adapted for colder conditions, but the hammock shelter itself does not determine your winter comfort. You need an appropriate underquilt, top insulation, rainfly configuration, and campsite protection. For severe winter or alpine conditions, a purpose-built four-season ground shelter may be more appropriate.
Is hammock camping better than tent camping?
Neither is universally better. Hammocks can be significantly more comfortable on rocky or uneven forest floors, while tents are much more versatile in treeless environments. Terrain should be one of the first factors you consider.
HillZero is a premium outdoor design brand focused on Livable Backpacking Tents. Its philosophy starts with a simple question: How can a backpacking tent be easier to carry, without making it harder to live in?
Rather than pursuing the absolute lowest possible weight, HillZero focuses on a more considered balance between carrying efficiency and the quality of time spent at camp. Its core principle, “Carry Less. Live Better.”, reflects a broader view of backpacking: the experience is not only about moving farther, but also about arriving, resting, organizing gear, waiting out weather, observing nature, and spending meaningful time outdoors.
Starting with the Scott 2P, HillZero is developing its Livable Backpacking approach around practical aspects of shelter design, including space utilization, ventilation, entry and exit, movement, privacy, and comfort during longer stays—while keeping weight within a reasonable range.
