The Seamless Burrow Bag is a characteristically innovative sleeping bag from Montbell. Made using the brand's very own EXCELOFT synthetic down, unlike regular down it'll keep you warm even in wet or humid conditions. Pair that with seamless construction, reducing the potential for air to escape and you've got a seriously airtight sleeping bag.

The interior features gathered quilts and elasticated stitching which hug and move with you as you sleep, keeping insulation close to the body and eliminating dead space without feeling restrictive.
