The Greylock 4 torso length 4-season underquilt is designed with current state-of-the-art features and is intended for the hammock user who is seeking an ultralight approach to bottom insulation. It is a dual differentially designed lightweight underquilt and has body contouring radial baffles. The Greylock 4 underquilt is effortless to attach and it will maintain its loft under any conditions. The Greylock 4 lightweight underquilt comes equipped with full length, channeled shock cord suspension that allows the user to make minor adjustments to their under quilt position. For those desiring to use the traditional JRB corner underquilt suspension the Greylock also comes equipped with corner mounting tabs. When filled with 800 fill power down this torso length under quilt weighs just 22 ounces.

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.

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.

Note: Torso length under quilt users typically use their sit pad or back pack as foot and lower leg insulation.

The Greylock 4 torso length lightweight underquilt works with most brands and DIY hammocks.

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.
