The Comfort Light SI series aims to hit that sweet spot of minimal weight and packed size but also offers great comfort. At 2 inches, this mattress is going to protect you from just about any less-than-perfectly flat terrain. Featuring a women’s specific shape that is wider at the hip and narrower at the shoulder, the exterior anti-slip print ensures you don’t slip when sleeping on sloping ground and the multi-function reversible high flow-rate valve allows fast and easy inflation and deflation.
