Shaped specifically for cold-weather women adventurers, the extra-thick Women's Ether Light Extreme is constructed with additional insulation compared to the unisex model. The XT Air Sprung Cells provide four inches of stability and comfort, while increased-density dual layers of THERMOLITE® insulation prevent convective heat loss and internal air movement.

  • 6.3 R-Value is perfect for cold weather adventures.
  • At four inches thick, Ether Light XT Air Sprung Cells provides a plush sleeping experience.
  • Dual-density layers of Thermolite® insulation (higher density than the unisex model) fill the inner space, preventing heat loss due to convection and internal air movement.
  • Lighter, quieter and durable 30D/40D face fabric with Sea to Summit’s liquid-extruded lamination is extremely reliable.
  • Quick and easy inflation, deflation and adjustment is made possible by our multi-function valve and supplied Airstream Pump/stuff sack.
  • Anti-microbial treatment added to the TPU lamination formula prevents internal mold growth.
  • PillowLock system prevents your Sea to Summit Aeros Pillow from slipping.
  • Comes with a stuff sack which doubles as a pump, a repair kit with six self-adhesive patches and a spare valve insert.


  • Shaped for comfort: Narrower at the shoulders, but wider between the hips and knees. This shape significantly enhances comfort for those who sleep in a figure-4 position (or on their sides or stomach) by giving them the room they need to move while they sleep.
  • Air Sprung Cells provide support: Air Sprung Cells provide a stable, supportive sleeping surface. Hundreds of individual air-filled springs (or ‘cells’) provide the kind of support you may be used to from a high-quality pocket sprung mattress. All sleepers – but particularly those who need hip and back support – will benefit from the stability that an Air Sprung Cell pad offers.
  • Quiet construction: Air Sprung Cell pads are quieter than air pads which use a reflective film in their construction. Less noise throughout the night means a better night’s sleep, night after night – Sea to Summit pads use stronger materials and more reliable technologies than other pads. Women’s Air Sprung Cell pads also feature more lofting insulation than the unisex version.
