The Roo Double is OutdoorGearLab's highest-scoring end-gathered hammock, pairing a buttery 40D recycled ripstop fabric with a 500-pound capacity, eight gear loops, and climbing-rated Kanga Claw carabiners. At 17 ounces of fabric it packs to the size of a peanut-butter jar. The catches: suspension straps cost extra, and the recycled fabric shows wear against rough bark.
Full review
Real-World Comfort
The Kammok Roo Double earns the top spot largely on the strength of its fabric. OutdoorGearLab, which scored it 79 out of 100, the highest of any end-gathered hammock in their 22-model test, praised it directly: 'the GravitasX 40D diamond ripstop fabric is noticeably softer, more flexible, and highly breathable for those hot summer afternoons.' The Good Ride agreed after extended testing, noting 'the hammock is comfortable to lay in, and the feel of the fabric was a positive feature, soft to the touch.'
At 10 feet long and nearly 6 feet wide, the Roo Double has enough room for one person to cocoon comfortably or two to share for an afternoon. The diagonal lay that makes any good gathered-end hammock flat and comfortable comes easily here thanks to the generous width. For a hammock you'll actually relax in for hours, fabric softness and width are what matter most, and the Roo leads the field on both.
Fabric and Hardware
Kammok's GravitasX fabric is 100% recycled, bluesign-approved, and treated with a DWR water-resistant finish, so it dries fast and resists light moisture, a meaningful advantage for a hammock that lives outdoors. The 40-denier weave is light at 17 ounces yet rated to 500 pounds, double the capacity some premium hammocks offer.
The hardware is where Kammok separates from budget competitors. The patented climbing-grade Kanga Claw carabiners are rated to a remarkable 4,720 pounds of force, far beyond anything you'll load them with, and they make setup a quick, confidence-inspiring clip. The hammock packs into an attached roll-top water-resistant stuff sack about the size of a jar of peanut butter, so there's no separate bag to lose.
Versatility
Eight small gear loops run along the fabric's sides, and they're more useful than they sound. They let you clip on accessories, a ridgeline organizer, a bug net, a light, or a rain tarp, turning the Roo from a simple day-use lounger into the foundation of a backcountry shelter system. OutdoorGearLab highlighted this expandability as a key reason the Roo scores so well: it's a hammock you can grow into rather than outgrow. Combined with the lifetime warranty, it's built to be a long-term piece of gear.
Where It Falls Short
The Roo Double's drawbacks are cost and a couple of fabric quirks. Suspension straps are sold separately, so the $95 hammock price isn't the whole story, you'll need to budget for straps to actually hang it. OutdoorGearLab also noted that 'the 100% recycled fabric did show some signs of wear when rubbing against tree bark,' a reminder to use proper wide tree straps rather than rough cordage. The Good Ride's tester mentioned occasional static electricity in very dry climates. None are dealbreakers, but they mean the Roo isn't the cheapest or most bombproof option here.
How It Compares to Alternatives
The Roo Double sits at the premium end of this group. The ENO DoubleNest is a touch cheaper and a proven everyday classic but uses a slightly stiffer 70D fabric and a lower 400-pound capacity. The Grand Trunk TrunkTech Double matches the Roo's softness and ultralight packability but lacks the gear-loop versatility. The Kootek Portable and Wise Owl Outfitters DoubleOwl are far cheaper and include straps, but their fabric and hardware aren't in the Roo's class. For buyers who want the best fabric, hardware, and expandability, the Roo justifies its price.
Long-Term Value
Two things make the Roo Double a sound long-term buy despite its higher price: the lifetime warranty and the recycled, bluesign-approved fabric that signals quality construction. Kammok backs the hammock from backyard to backcountry, and the climbing-rated hardware is engineered to outlast the fabric. For a camper who hammocks regularly and wants gear that lasts, the per-year cost is low, and the gear-loop system means the Roo can serve as a day lounger now and a full shelter base later. The straps-sold-separately model is the main asterisk on the value story, so factor that into the comparison against the strap-inclusive budget hammocks.
Who It's Best For
The Roo Double is for the camper who wants the best-reviewed gathered-end hammock and values soft fabric, strong hardware, and the ability to expand into a shelter system, and who is willing to pay a premium and buy straps separately. It's an excellent solo cocoon and a comfortable two-person lounger. Budget buyers who just want to hang and relax should look at the strap-inclusive Kootek Portable or Wise Owl DoubleOwl, and shoppers who want a proven everyday classic at a slightly lower price will like the ENO DoubleNest, but for top-tier quality the Roo is the pick.
