Description

Designed especially for 3-season backpacking, the Sea to Summit Ether Light XT Insulated Mat offers a 4”-thick sleeping base, has a 3.8 R-Value, and weighs just a few ounces over a pound. An innovative pump sack makes inflation fast and easy.

Interconnected chambers formed by a dot-welded pattern, the pad’s unique Air Sprung Cells create a supportive sleeping base that better conforms to your sleeping body than traditional vertical or horizontal baffles.

Dual thermal technologies equip the pad for use in colder temperatures. A lightweight, non-woven metalized fabric, Exkin Platinum prevents convective heat loss. This pliable fabric is also quieter than some “crinklier” fabrics used to achieve heat reflectivity. A layer of Thermolite insulation adds enhanced warmth.

A stand-out feature on Sea to Summit pads is the low-profile multi-function valve. A one-way design allows for fuss-free inflation and an internal button lets you make micro adjustments to firmness. A larger port beneath the top portion of the valve makes deflation quick and easy. Additionally, by setting flush to the surface of the pad, the valve also cuts down on potential warranty issues. A pump sack is built into the included stuff sack, making inflation easy and keeping moisture out of the interior of the pad.

The Sea to Summit Ether Light XT Insulated Mat is available in your choice of Regular (72" x 21.5”), Regular Wide Rectangular (72" x 25"), Large (78" x 25"), and Large Rectangular (78" x 25") size options.

Good for warm weather

Likes

Very comfortable mat. Lightweight! Sturdy material & quiet. The welds on the fabric seem to be very sturdy.

Dislikes

At 38 degrees in my Western Mountaineering 25 degree Terralite, I was feeling cold spots on my hips, back, shoulders. I'm afraid the large air volume is difficult to insulate. Better for warmer weather.

Luxurious and Light - sort of

Likes

Transitioning from the neoair xlite and was looking to sacrifice some ounces for a more comfortable night's sleep. Enter the ether light xt insulated. This pad is supremely comfortable and feels quite durable. The "air sprung cells" really hug your body and feel quite stable. Being an active sleeper I always felt like being on the neoair was a bit of a balancing act. I have yet to experience the "warmth" factor but that point is typically irrelevant because there are too many variables that affect our sleeping comfort (temp wise). I'm grateful that all manufacturers are mostly adhering to r-values now. Blowing up this pad with the included stuff sack/pump sack couldn't be easier.

Dislikes

There aren't many but the big one is WEIGHT. I knew going in from previous reviews on other platforms that S2S's weights were wrong. There was no exception here. S2S's claimed weight was 19.4 oz for the pad alone (the rectangular regular wide). My pad weighed 21.5 oz. This did not include the stuff sack or the pillow lock strips. This was disappointing. It's still a great pad but I wish the weights had been more accurate.
