UL Spiral Down Hugger #1, regular

15oF 800 down fill, spring/fall sleeping bag

Montbell has incorporated a classic tailor's technique to address sleeping bag comfort issues. By integrating a woven fabric "cut on the bias" and orienting the fabric's warp and weft threads at 45 degrees to major seam lines the sleeping bag becomes more fluid or elastic in nature. Additionally, "spring like" crimped fibers are used in the weave of the fabric to capitalize on their inherent stretch properties. The result is a flexible sleeping bag that makes "tent life" more bearable without the additional weight and fabric required in Montbell's plush Super Stretch™ System.
