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.


Woven fabrics typically do not stretch vertically or horizontally without the utilization of heavy elastic materials. However, when stressed along the diagonal the same fabric will show stretch characteristics.

The history and evolution of Montbell sleeping bags

For overnight hikes or long trails, a good night's sleeping is extremely important. If fatigue carries over to the next day due to a lack of sleep, it can contribute to an inability to concentrate, which could possibly lead to a stumble and maybe even injury. "Warmth" especially is a crucial element that can determine whether or not you get a good night's sleep. Montbell's president Fumiaki Masaki will take us through a history of sleeping bags in Japan, the transitions in insulating materials, design and functionality, and the ever important concept of "warmth".
