"The Wooki® underquilt is our full-length down underquilt for the Blackbird, Blackbird XLC, Eldorado, Traveler and Traveler XL hammock models.
 
Note: the Wooki does not have a reversible lay, it is configured for a head left/feet right lay, we can make a “reverse-lay” configuration but you must order it through the custom underquilt section.
 
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).

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. Ask us for details if this is your intention."
