A great combination of high quality goose down, light weight materials, and the supreme comfort of the Super Spiral-Stretch System. SUPER SPIRAL-STRETCHTMSYSTEM (Pat. Pending) MontBell has adapted a classic tailor's trick by integrating a woven fabric "cut on the bias". 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, coiled or crimped fibers are used in the fabric weave to capitalize on their inherent stretch properties. To create an even more comfortable system we utilize an elastic stitch technique to create small "gathers" in the quilting. By combining this stretchy fabric, strategic seam orientation, and the elasticized gathers we offer unrivaled fit and comfort. These innovations allow the sleeping bag to stretch with you as you change positions throughout the night, drawing the insulation closer to your body and eliminating drafty dead spaces. Keep body heat inside your sleeping bag, where it belongs. 800Fill Power Goose Down 12-denier Ballistic Airlight Elite water-repellent performance Size: R/ZIP/ L/ZIP Color: PRSI(Persimmon) Weight: 3 lbs. 7 oz.

They found that integrating a woven fabric "cut on the bias" and orienting the fabric's warp and weft threads at 45 degrees to most major seam lines the sleeping bag becomes more fluid in nature. To create an even more comfortable system they utilize an elasticized thread in the stitch to create small "gathers" in the quilting. Through the combination of strategic seam orientation and the stretch provided by gathered quilting they offer unrivaled fit and comfort. These innovations allow the sleeping bag to move with you as you change positions throughout the night, drawing the 800 fill goose down closer to your body and eliminating drafty dead spaces. Keep body heat inside your sleeping bag, where it belongs.
