Sea to Summit Ether Light XT Extreme Insulated Rectangular Air Sleeping Mat

A plush sleeping cushion built for the coldest conditions, the Sea to Summit® Ether Light XT Extreme Insulated Rectangular Air Sleeping Mat offers comfortable warmth in a lightweight package. A great pad choice for cold weather backpackers and campers, this 4"-thick pad employs dual-density layers of Thermolite® HL-1 insulation to offer the warmth for true 4-season use. This advanced insulated design fill the pad's inner space, preventing heat loss due to convection and internal air movement. Still offering a plush and comfortable sleeping surface, this pad utilizes Ether Light XT Air Sprung Cells for unmatched cushion. Employing dozens of small interconnected chambers to support your weight and conform to your body contours, XT Air Sprung Cells use loops of TPU material to connect the top and bottom welds for a thicker cell that offers even greater support and insulation. These advanced features work together to give the mat an R-Value of 6.2 to help you take on cold weather adventures. Made of a lightweight, quiet, and durable 30- and 40-denier nylon with liquid-extruded thermoplastic polyurethane (TPU) lamination, this mat resists delamination for multiple seasons of reliable use. Inflation and deflation is made easy by the UltraLight's multifunction valve and included Airstream Pump/stuff sack. Compatible with Sea to Summit camping pillows featuring the Pillow Lock™ System (not included). Features treatments added to resist internal mold growth. Includes repair kit with 6 self-adhesive patches and spare valve insert.
