Sleeping pads provide two vital functions: cushioning and insulation. No matter how great your sleeping bag is- virtually all of its insulating properties are lost when crushed beneath your body so that even on a warmer night all of your heat is lost through the cold ground. Gossamer Gear pads are designed with the backpacker in mind; keeping weight off your back, with maximum protection from the cold temperatures. Our foam pads can be used with all backpacking sleeping pads on the market, to provide valuable insulation in cold weather conditions, superb in winter for snow camping. Some mats are cut to fit in the back panel sleeve of select backpacks for comfort and act as a multi-use item. A hiker can use them as a back pad or roll them to store inside or on top of our ultralight packs. Our most popular model, the Sitlight, is a big hit for day hiking and backpacking. Just simply remove it from the backpack and now you have a comfortable trail seat!
