We've designed these to be compact and comfortable. We shed a few grams by using a light foam with vertical and horizontal cut-outs. The rectangular shape with rounded corners feels roomy on the ground but takes up little room in your pack. The 3.8cm thickness keeps the chill away through four-season use. The big valve makes it easy to deflate, and closes again with a simple twist.
