Our custom Wooki-builder allows you to customize your Wooki underquilt for your hammock with more options than what are available on our stock Wooki page. You have more color options and more temperature rating options. Recently updated design (10/1/25) The Wooki® is our full-length down underquilt. It covers the entire bottom of your hammock, but the insulated portion only covers the part you actually lay on, which saves weight and bulk by putting insulation only where it’s needed. The Wooki doesn’t require any adjustment because it fits just like a hammock, it’s essentially a lightweight insulated hammock that slips over your actual hammock. You simply set it and forget it. It features secondary suspension loops (HVAC loops) allowing it to be vented in warmer weather and also to facilitate stacking 2 quilts together to create a warmer quilt if needed. The Wooki-10 (for 10 foot hammocks) fits users up to about 6 feet tall. The Wooki-11 (for 11′ hammocks) fits users up to 6’6″ tall. The Wooki® underquilt features a dual differential cut 15 denier high threadcount PFC/PFAS-free C0 DWR ripstop nylon shell, and is overstuffed with 850-fill Expi-Dry Gold PFC/PFAS-free DWR goose down which meets the RSD certification (Responsible Down Standard). As for the fabrics, the 10d fabric is our ultralight option, the 20d is the heaviest and offers the most durability and the 15d is a great compromise between the two and is by far our most popular. 15d and 20d fabrics use PFC/PFAS free DWR. Sewn in the USA by Warbonnet The Wooki-10 fits: 10 foot hammocks such as our: Original Blackbird Travelers (non XL versions) The Wooki-11 fits: 11 foot hammocks such as our: Blackbird XLC Eldorado Traveler XL It is possible to use the Wooki on similarly sized non-Warbonnet hammocks as well, the suspension of the Wooki can be lengthened slightly to make this down underquilt fit a longer hammock.
