>>2776835I hammock camp in freezing temps all the time. The trick is to 1) use down under + over quilt, synthetic won't work 2) fit your underquilt properly so it's lofted but not creating gaps under your back 3) if needed, stop excess drafts with a better (walled) tarp and/or underquilt protector
pound to pound hammock camping works better for cold temps because you can surround yourself with lofted down and not lose heat to a cold ground. but at the same time if you don't fit your quilt right you will lose a tremendous amount of heat to drafts
you can also add a thermal pad I guess but I've never tried it. an underquilt protector (picrel) was all I needed to dial in my setup to keep me warm in very cold conditions
