Continuous-filament synthetic insulation provides reliable warmth for the life of a sleeping bag, even in damp conditions. We build the Rosa with Climashield HL, and wrap the whole package in 70-denier nylon for a durable bag destined for seasons of use. Rated to 20 degrees, the Rosa not only provides warmth, but serious comfort, too - an ergonomically shaped foot box wont cramp your feet and Pad Locks mean you wont roll off onto the hard ground during the night. Check out the images to the right to see the Lavender Blue color options. A full-length draft tube insulates along the zipper, retaining heat and helping you stay warm through the night.
