The 10cm thick Ether Light XT Extreme Insulated Air Mat-Large redefines lightweight sleeping comfort for winter trips with an R-value of over 6.2.

The Air Sprung Cells from Sea to Summit are the reason you’ll have one of the most comfortable nights sleep. The mat conforms to your body shape since each Air Sprung Cell deforms separately. This gives support and comfort by dividing the weight more evenly.

TPU loops securely holding the top and bottom layers together are designed in a way to allow these layers to be separated farther, resulting in greater air pockets when inflated, which is ideal for side sleepers. This design also uses less fabric in general, resulting in more stability and comfort for less weight.

The Air Sprung Cells are filled with dual-density layers of THERMOLITE insulation that work together to reduce convective heat transmission and improve warmth while staying lightweight and packable.
When the temperature lowers, the 6.2 (women’s 6.3) ASTM R-value of the Ether Light XT Extreme will keep you cushioned and protected from the cold hard lumps and bumps beneath.

Features

  • Extra thick and exceptionally warm-10cm of backpacking sleeping comfort for extreme conditions
  • ASTM R-value 6.2 is designed for cold-weather use
  • Dual-density layers of THERMOLITE insulation
  • Extra thick (XT) Air Sprung Cell construction for 10cm stable comfort
  • Lightweight, quiet and grippy 30/40D Nylon face fabric
  • Field repairable with included self-adhesive patches
  • Ultra-Fresh anti-microbial treatment added to the TPU formula prevents internal mould growth
  • Pillow Lock attaches an Aeros pillow to mat
  • Quick and easy inflation, deflation and adjustment with the multi-function, high flow-rate valve and supplied Airstream Pump Sack
