By adopting a classic tailor's trick and paring it with high grade materials MontBell has brought extreme comfort and thermal efficiency to the light weight backcountry enthusiast. We 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 we 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 we offer unrivaled fit and comfort. These innovations allow the sleeping bag to move with you as you change positions throughout the night, drawing the hydro-phobic insulation closer to your body and eliminating drafty dead spaces. Keep body heat inside your sleeping bag, where it belongs.

SUPER SPIRAL-STRETCH SYSTEM

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, 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. 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. By using a sleeping bag with Super Spiral technology you keep body heat inside your sleeping bag, where it belongs.
