Offering a plush sleeping cushion with 3-season insulating performance, the Sea to Summit® Ether Light XT Insulated Rectangular Air Sleeping Mat offers comfortable warmth in a lightweight package. A great pad choice for backpackers, campers, long-distance cyclists, and more, this 4"-thick pad utilizes Ether Light XT Air Sprung Cells to provide a plush sleeping experience. Employing dozens of small interconnected chambers to support your weight and conform to your body contours, XT Air Sprung Cells use loops of thermoplastic polyurethane (TPU) material to connect the top and bottom welds for a thicker cell that offers even greater support and insulation. Reflective Exkin Platinum® Insulation and convective Thermolite® HL-1 Insulation work in tandem in this pad to minimize heat loss for optimal comfort. These advanced features work together to give the mat an R-Value of 3.2, making it a great pad choice from late spring to early fall. Made of a lightweight, quiet, and durable 30- and 40-denier nylon with liquid-extruded 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.
