Since 1975, Montbell has been innovating and creating better outdoor sleeping experiences with our sleeping bags. The Seamless Down Hugger series came about when we asked ourselves How can we improve the down's ability to insulate?" When fully lofted, down traps air which provides insulation. The more air in the sleeping bag, the better it insulates. We began scrutinizing the elements of the sleeping bag that affect lofting ability. An idea proposed was to eliminate the baffles. Without baffles, the down would be unhindered and could loft to its fullest potential. But baffles prevent down from shifting and developing cold spots. Our next hurdle was developing a baffle replacement. Mother Nature provided inspiration and we developed a specialized thread called Spider Yarn. By placing a web-like layer of polyester yarns throughout the bag, we created a system that traps down and holds it in place. The "Spider Baffle System" was successful in maintaining a set amount of down, though a majority of the down is still able to move freely inside the bag. Although weve eliminated most of the exterior sewing lines, the interior features gathered quilts and elasticized stitching to promote comfort. The WR lineup utilizesGORE-TEX INFINIUM WINDSTOPPERwith seam sealing to create a weatherproof sleeping bag for use in variable conditions.
