This four-season pad suits sleeping out while ski touring or any cold-weather expedition. It’s got the same tapered cut and rounded corners as three season versions, but the foam is thicker and the pieces are diagonally cut rather than punched out. This difference reduces the weight and limits the amount of heat you lose to convection.
- 75-denier polyester top with a 70-denier, tough nylon bottom. Extra coating on the bottom increases its durability.
