Seamless Burrow Bag
Seamless construction allows us to maximize insulation's lofting ability. For our synthetic insulated sleeping bags, it's the perfect pairing. Standard synthetic insulation is prone to tearing. To prevent tearing, standard synthetic insulation must be sewn in place so the fibers don't pull apart in the course of normal usage. EXCELOFT on the other hand doesn't have the same issues because the unique blend of fibers causes the fibers to adhere to each other. As a result, sewing EXCELOFT in place isn't as necessary. This reduces sewing holes where warm air can escape and creates a more airtight sleeping bag. As a result, this simpler method of construction allows EXCELOFT to loft to its fullest potential, trapping more warm air and reducing the amount of cold spots associated with Sewn Through Construction.
Excelent Stretch to Provide Better Sleep (Burrow Bag)
The Spiral Stretch System (US.Patent No.7,900,301) is what made Montbell sleeping bags famous. The ability of the bag to move with you during the night has provided comfort for many. Our sleeping bags featuring seamless construction are no different. Although the exterior of the bag is a solid piece of fabric, the interior of the bag features a combination of the fabric's mechanical stretch and elastic stitching. The result, the sleeping bag hugs and moves with you as you sleep, but doesn't feel restrictive. This also means that as you move, gaps between you and the sleeping bag are less likely to form and maintains even coverage of the sleeping bag, maintaining your warmth.

Tapered Spiral Stuff Sack
Utilizes the same bias cut fabric used for our Spiral Stretch System. Because the fabric stretches, it's possible to alter the shape of the sleeping bag to some degree so it fits in the available space of your backpack. The opening to the stuff sack is wider to enable easier stuffing.
