Sea to Summit Ether Light XT Extreme Cold-Weather Insulated Sleeping Pad - 4" Thick, 72" x 25" Rectangular Camping Mat for Backpacking, Hiking & Winter Adventures - Lightweight & Compact for Outdoor Enthusiasts

The Ether Light XT Extreme is extra thick and exceptionally warm. The XT Air Sprung Cells provide four inches of stability and comfort, while dual-density layers of THERMOLITE® insulation prevent convective heat loss and internal air movement. This results in true four-season performance. Features 6.2 R-Value is perfect for cold weather adventures. At four inches thick, Ether Light XT Air Sprung Cells provides a plush sleeping experience. Dual-density layers of Thermolite® insulation fill the inner space, preventing heat loss due to convection and internal air movement. Lighter, quieter and durable 30D/40D face fabric with Sea to Summit’s liquid-extruded lamination is extremely reliable. Quick and easy inflation, deflation and adjustment is made possible by our multi-function valve and supplied Airstream Pump/stuff sack. Anti-microbial treatment added to the TPU lamination formula prevents internal mold growth. PillowLock system prevents your Sea to Summit Aeros Pillow from slipping. Comes with a stuff sack which doubles as a pump, a repair kit with six self-adhesive patches and a spare valve insert.
