Expert Opinion

Ether Light XR

"I highly rate the storage system and bag and the bag quickly turns into your airstream pump inflation bag. Once you have mastered the art of the inflation bag this is an amazingly efficient system for inflating the Ether Light XRThis mat is super comfortable and light weight. I love integrating the sea to summit pillow system with this mat for really good nights sleep in the hills."
