About The Product
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.
Product Features
- 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.

DESIGNED FOR WOMEN
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.
