Jacks R Better designed the first hammock underquilt in May 2004. We continue to optimize our underquilt designs based on our real-world experience. We offer the best underquilt on the market.

How Does An Underquilt Work?

Hammock Underquilts provide better insulation underneath you than a sleeping bag. Sleeping bags do not work in a hammock because insulation only works when it has the ability to loft.  A sleeping bag’s insulation compresses under your body weight reducing its loft.  In a hammock, this leads to convective heat loss from the cold air stripping away body heat. An underquilt hangs outside the hammock allowing down to loft fully.

Hammock Underquilts work better than a sleeping pad in a hammock. Keeping a sleeping pad under you in a hammock is a constant struggle. Sleeping pads made of non-breathable materials cause you to sweat creating dampness in your clothes causing a chill as you cool off.

All Jacks R Better underquilts are optimized with a 25% overstuff to reduce down migration and enable the underquilt to maintain its rating when the down losses loft between cleanings. All of our underquilts work on any hammock including all gathered end and bridge hammocks.

Features

  • Hammock Underquilt Fit – Jacks R Better hammock underquilts work on all gathered end and bridge hammocks. Such as ENO Hammocks, Hennessy Hammocks, Warbonnet Hammocks, Dutchware Chameleon, and most other brands and DIY hammocks.
  • Down –Nikwax Hydrophobic-Down™ The safe, high-performance, PFC-free, water-resistant down fill for outdoor clothing and gear. As a result, it keeps users warmer and drier in a wider range of conditions.
  • Overstuff: All Jacks ‘R’ Better hammock underquilts are optimized with a 25% over-stuff. Overstuff reduces down migration and enables the quilt to maintain its rating if the down loses loft between cleanings. Consequently, we do not recommend any additional over-stuffing.

How to properly hang an underquilt:

  • Hang tight enough to prevent any air gaps between it and the hammock.
  • Not too tight that the down can not fully loft (differential baffles prevent this).
  • The underquilt should be hung tight enough to slightly lift the hammock when you are not in it.
  • Pull the end cords just tight enough to seal off the ends of the quilt but not too tight.
