When insulation, comfort, and a small and light packed size are essential, the EtherLightXT Extreme Women’s Mat from Sea to Summit will tick all those boxes and more.

This model takes the design of the original bestseller from the brand and increases the warmth while giving it a women’s specific fit for cold weather expeditions. The Air Sprung Cell construction conforms to your body for support, providing 10cm of stable comfort with a quiet and grippy 30/40D nylon face fabric surface. There are dual-density layers of THERMOLITE® insulation that gives it an ASTM R-value of 6.3 for warmth and it features an anti-microbial treatment to prevent mould from growing inside. Inflate, deflate, and adjust without a hassle thanks to the multi-function valve, and get help setting it up using the handy airstream pump sack that’s integrated into the stuff sack.

To keep your existing compatible Sea to Summit pillow from sliding around at night, there’s a PillowLock™ system, and for repairs in the field, there are self-adhesive patches included. When a wintry adventure is on the cards, sleep soundly and warmly on the EtherLightXT Extreme Women’s Mat from Sea to Summit.
