Kammok Mantis UL All-in-One Hammock Tent Review (2026)

An all-in-one shelter system

The Mantis UL ships as a complete kit rather than a bare hammock: Kammok includes the hammock body with suspension straps and carabiners, an integrated full-length bug net, a structural ridgeline, a rainfly with guy lines, six stakes and a dual-compartment stuff sack. That means a camper can buy one product and head out with everything needed for a night off the ground, rather than piecing together a hammock, netting and tarp from different brands that may not fit together cleanly. For campers who want the simplicity of one purchase and one setup routine, this all-in-one approach is the main reason to choose the Mantis UL over a basic hammock.

Weight, materials and capacity

Kammok rates the complete system to hold up to 300 pounds and lists a packed weight of about 2 pounds 4 ounces for the full kit including rainfly, ridgeline, bug net and stakes. The hammock body uses Levitas 20D nylon diamond ripstop with a DWR finish, while the rainfly is cut from Patagium 15D nylon ripstop treated with a 1,500mm PU, silicone and DWR coating for weather resistance. The bug net uses Dragonet mesh with a clear Stargazer panel that lets you look up at the sky through the netting. The hammock itself measures 120 inches long by 56 inches wide, and the rainfly spans 136 by 88 inches, tapering to 72 inches at the foot end for full weather coverage.

Setup and learning curve

Because the Mantis UL combines several components most campers pitch separately, first-time setup takes longer than hanging a simple hammock, since you are adjusting suspension straps, tensioning the structural ridgeline, and staking out a rainfly all at once. Reviewers of the system generally note that setup becomes quick once you have practiced it a few times at home or on an early trip, but the first attempt in the field is not the moment to learn the process. Anyone new to hammock camping should expect to spend some time dialing in strap angle and rainfly tension before the system pitches as smoothly as its packed size suggests.

Using it without trees

One advantage of the Mantis UL's all-in-one design is that it can pitch as a ground shelter using the tarp and stakes in a bivy-style setup when there are no trees available, rather than being unusable in open or treeless camping spots. Kammok also sells a separate Outpost portable hammock stand as an accessory for campers who frequently camp somewhere without trees and want a dedicated stand instead of improvising a ground pitch. This flexibility extends the system's usefulness beyond forested campsites, though a stakes-and-tarp ground pitch will not feel as stable or comfortable as hanging the hammock between two solid anchor points.

Verdict and who should look elsewhere

The Mantis UL earns its place for campers who want a genuinely complete, lightweight hammock shelter and are willing to pay a premium for materials and design that shave weight without cutting the bug net, rainfly or suspension. It suits backpackers moving to hammock camping who do not want to assemble a system from separate parts, and campers who value being able to pitch on the ground when trees are not available. Casual car campers who only need an occasional backyard or car-camping hammock, or anyone on a tight budget, will likely get more value from a simpler standalone hammock and a separate budget tarp instead of this complete but expensive system.
