No more wrestling with pads inside the hammock. No more waking up cold in the middle of the night. The Mt. Washington 4 winter 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.
Over-stuff: 25% over-stuff included!
All Jacks ‘R’ Better quilts are over stuffed by at least 25%. We do not recommend additional over stuffing. If you think you need additional over-stuff consider purchasing the next warmer quilt model.
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 under quilt 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 winter underquilts.
Activ-dri down™ – Activ-dri™ is a hydrophobic down treatment that keeps the down drier, while having no adverse effects on loft, fill power, or warmth retention. Activ-dri down is still down insulation and should be protected from direct exposure to moisture. All types of insulation, whether down or synthetic, will degrade in insulation capability if wetted.
