The Sea to Summit Women's Ether Light XT Extreme is 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.

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.
• 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.
