Highest performance synthetic bag on the market. Thermally mapped insulation and half-length center zip maximize efficiency. Engineered to be the lightest and warmest synthetic bag on the market. Lamina™ construction welds the Thermal.Q® insulation to the shell and lining, eliminating the cold spots caused by traditional stitching. By mapping different insulation weights throughout the top of the bag we are able to concentrate warmth where you need it most – around your core and feet. Thermal efficiency is optimized by a performance mummy-cut, face gasket and single center half zip.

About Mountain Hardwear

Mountain Hardwear was founded in 1993 by a small band of outdoor industry iconoclasts. They saw the industry changing, compromising quality and dumbing down products to serve less technical users. Mountain Hardwear was founded to buck this trend in order to stay true to the needs of outdoor athletes.
