Warm, comfortable, and lightweight rectangular pad; R-value 6.2
Sea to Summit has taken their best-selling Ether Light XT mat and increased the insulation to make it warmer for when the mercury drops. With an R-value over 6, the 4" thick Ether Light XT Extreme air mat redefines lightweight sleeping comfort for winter adventures around the globe.
Sea to Summit's Air Sprung Cells are the reason you will sleep better on their air mats. Each Air Sprung Cell deforms independently and allows the mat to conform to your body shape. This provides support and comfort by more evenly dispersing pressure across the mat’s surface. Dual-density layers of THERMOLITE® insulation fill the Air Sprung Cells and work together to prevent convective heat transfer and boost warmth while remaining lightweight and packable.
