Why We Love It

The top performing synthetic bag you'll find anywhere. Thermal.Q synthetic insulation lets this bag excel in wet conditions without losing insulating ability. It features outstanding compressibility, high loft and light weight. Different insulation weights are mapped throughout the top of the bag to concentrate warmth where you need it most – around your core and feet. Thermal efficiency is maximized by a performance mummy shape, face gasket and single center half zip.
