Winter demands heavier layers and a thicker sleeping bag. Offset that extra weight with the warmest ultralight mat around. The awesome down insulation lets you bed down on snow and cold surfaces and sleep warm through a long night.

• Down fill packs small, lofts big and insulates incomparably.
• I-beam baffles add stability so you don't roll off in the night.
• Tapered profile couples with a second mattress, head to toe, in tight spaces.
• Single flat valve doubles for inflation and deflation to save weight and space.
• Includes the Exped Schnozzel pump bag for fast, moisture-free inflation.
