Product Description

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 we’ve eliminated most of the exterior sewing lines, the interior features gathered quilts and elasticized stitching to promote comfort. The WR lineup utilizes GORE-TEX INFINIUM™ WINDSTOPPER® with seam sealing to create a weatherproof sleeping bag for use in variable conditions.

Details

900 Fill Power EX Down

Fill power refers to the volume in cubic inches that 1 ounce of down will displace. All other things being equal (fabric, construction method, and fill amount), a product made with high fill power down (900) is lighter and more compressible than an equally warm one made with lower quality down (550).

Offering sweet dreams with superior stretch and comfort for all shapes and sizes

By orienting the fabric’s warp and weft threads at 45 degrees to most major seam lines the sleeping bag becomes more fluid or elastic in nature. Additionally, to create an even more comfortable system we utilize an elastic stitch technique to create small “gathers” in the quilting. By combining the strategic seam orientation and the elasticized gathers we offer unrivaled fit and comfort.

About the material: 7-denier BALLISTIC AIRLIGHT®

Ballistic Airlight® is made using the same nylon polymer as our Ballistic® material and a highly technical production process to create extremely fine, super thin threads. These threads are then woven into ultralight, gossamer fabrics that share the same characteristics as Ballistic®: one and a half times more abrasion resistance than other similar weight fabrics and boasts three times the tear strength of nylons that are almost 20% heavier. Additionally, Ballistic Airlight® is often woven using different techniques to create fabrics with radically different characteristics, such as fabrics that allow the garment to stretch or fabrics that "breathe" to release built up heat and moisture.
