Sea to Summit Ether Light XT Regular – Extra-Thick Backpacking Air Mattress (72 x 21.5 x 4 in)

Sea to Summit Ether Light XT Regular: Extra-Thick Backpacking Comfort

The Ether Light XT Regular blends light weight with a notably plush sleeping surface, making warm-season adventures more comfortable in a compact footprint. At four inches thick, it creates a soft, supportive feel that helps you settle in after a long day of hiking, biking, or trail exploring. The Air Sprung Cell construction mimics a traditional spring mattress by increasing the contact area with your body and evenly distributing pressure, which many campers find helps reduce pressure points and promotes steadier sleep on uneven ground.

Designed for side sleepers and those who crave a cushier lay, the pad uses a single-layer design with flexible loops that form large air pockets for a plush, forgiving surface. The non-slip 30D/40D nylon face fabric stays quiet on tent floors and resists shifting, enhancing stability through the night. This combination of materials and structure aims to deliver a calm, restful rest without adding unnecessary weight to your pack.

Fast, controlled setup for on-trail comfort

A multi-function valve, paired with the integrated Airstream Pumpsack, lets you inflate the mat in just a few breaths. One-way deflation supports quick packing, while you can fine-tune air pressure to taste for a balanced mix of firmness and cushioning. This setup supports a straightforward transition from camp to trail, especially after a long day when you want to get off your feet quickly.

• Extra-thick 4-inch profile delivers a softer feel without a heavy load, ideal for warm nights.
• Air Sprung Cell construction improves body contact and evenly distributes pressure for restful slumber.
