No more waking up cold in the middle of the night! The Mt. Washington 4 hammock underquilt works on any hammock – including all gathered end hammocks and bridge hammocks. It attaches to a hammock in under a minute with the included JRB Suspension System.

All Jacks ‘R’ Better quilts are over stuffed by at least 25%. We do not recommend additional over stuffing.

Compression Sack: A lot of folks no longer use compressions sacks and instead keep their quilts dry inside a lawn contractor bag or trash compactor liner. We do not want anyone to have to pay for something they do not want so now we offer them separately. For 0 degree quilts we recommend the large size compression sack.

The Mount Washington 4 hammock underquilt works on ENO Hammocks, Hennessy Hammocks, Warbonnet Hammocks, Dutchware Chameleon, as well as most other brands and DIY hammocks.

Mt. Washington, at 6288 feet, is the home of the world’s worst weather: bitter cold, heavy fog, deep snow, and incredible wind … occasionally a beautiful day. To tackle the winter’s worst conditions, Jacks ‘R’ Better has designed a unique hammock underquilt with a dual differential cut, body contoured design and constant height radial baffles to achieve a 0 degree capability. These are the most capable and warmest commercially available hammock underquilts.
