Seamless Construction [Burrow Bag, Alpine Burrow Bag Series]

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.
