OutdoorGearLab scored the Kammok Roo Double 79 out of 100 and named it its Best Everyday Lounger, calling it one of the most comfortable hammock designs it tested. The outlet credits the soft GravitasX 40D diamond ripstop fabric, the Dyneema attachment cords and climbing-rated carabiners, and eight gear loops for adding accessories. Suspension straps are sold separately, and OutdoorGearLab saw the fabric show some wear when rubbed against tree bark.
Full review
Soft recycled ripstop and a roomy cocoon
OutdoorGearLab's Trish Matheny rated the Roo Double 8.0 for comfort and described it as one of the most comfortable hammock designs in the test. The review singles out the GravitasX 40D diamond ripstop as noticeably softer, more flexible and highly breathable, with a crinkle-free and DWR water-resistant treatment that dries quickly.
The outlet measured the hammock at 10 feet long and reports it is spacious enough for one person to wrap up in or for two people to share. Testers found it comfortable both lying horizontally and sitting upright, and noted no aches after extended afternoon naps.
Setup takes minutes, but straps cost extra
Ease of setup earned a 9.0 from OutdoorGearLab. Its testers never consulted instructions and had the hammock assembled in minutes, clipping the carabiners to straps girth-hitched around trees 15 to 20 feet apart.
The catch is that the straps are not in the box. OutdoorGearLab bought Kammok's Python 10 straps separately for testing and lists 'suspension straps sold separately' among its reasons to avoid. Kammok's own product page confirms the package holds the hammock, two Dyneema Racer Slings and two Kanga Claw carabiners.
Strong hardware, softer fabric
Durability and protection is the lowest of OutdoorGearLab's sub-scores at 6.5. The review praises the climbing-grade Kanga Claw carabiners, which it says can support up to 4,720 pounds of force, and the 500-pound capacity, which testers exceeded without creaking or shifting.
The concern is the fabric. OutdoorGearLab reports that the recycled material showed some signs of wear when rubbed against tree bark and questions how well the softer, more supple weave will hold up over time. The hammock carries a lifetime manufacturer warranty.
Gear loops for building a shelter
OutdoorGearLab scored versatility 8.0, pointing to eight small gear loops along the sides. They can hold small items off the ground or attach an underquilt, bug net, tarp or gear sling, all sold separately. The attached stuff sack hangs at the middle of the hammock and doubles as a pocket for a phone or snack.

How it compares
OutdoorGearLab measured the Roo Double at 24.0 oz with straps, lighter than the 31.0 oz it measured for the ENO DoubleNest with straps. Its 500 lb capacity matches the Wise Owl Outfitters Kit and is above the DoubleNest's 400 lbs. Like the DoubleNest it ships without tree straps, while the Wise Owl kit includes two 9-foot straps. It has no bug net, which the Warbonnet Ridgerunner builds in.
