Inflating

The Ether Light XT Insulated pad comes with their Airstream pump sack. It makes it so easy to inflate the sleeping pad. One of the reasons I quit using inflatable pads on backpacking trips, was because I hated blowing them up. Using the Airstream sack that comes with it, it took me only 3 breaths to fill the entire sleeping pad up. It is very easy to use and doesn’t sacrifice that much weight or space in the pack to bring it along.

Women’s Specific Construction

The shape, insulation and construction of the Women’s Ether Light XT is specifically created for women. Some of these features include “higher-density Thermolite® insulation (compared to the unisex model) to prevent convective heat loss, laminated to Exkin Platinum® – which reflects radiant heat” . The shape is slimmer in the shoulders and wider in the hips and knees.

Comfort

I found the sleeping pad to be very comfortable. It is thick enough for side sleeping, and heavier people as well. There is plenty of support and comfort, and I didn’t have the bag deflate on me at all throughout the night.

The effect of the insulation and the radiant heat was very apparent. If I moved slightly off the bag during the night, I instantly felt the cold air coming up from the ground. It made all the difference when sleeping on cold ground, or a cold van floor.

Warmth

I tested the sleeping pad with two other Sea To Summit bags. The Women’s Flame IV 15F, and the Spark SpIII 29F. In both cases, the insulated pad helped add warmth and comfort to the sleep system.

I normally run very cold during the night and just have learned to deal with it while camping. So, I always sleep in a down jacket, and put a hot water bottle at my feet for added warmth. I did neither of these when testing these sleep systems. And I was quite nervous to sleep without my backup warmth but committed to sleeping in normal layers to see if everything kept me warm. It was amazing to actually be comfortable most of the night. The only time I got cool feet, was at 3am when the fog rolled in and temps dropped for a couple hours. But I still stayed warm enough to continue sleeping.

Packability

The pad is really easy to deflate. The air comes out quickly and easily once the air plug is pulled. It rolls up nicely and takes minimal effort to fit it back into the stuff sack.

Overall

The Sea To Summit Women’s Ether Light XT Insulated Sleeping Pad provides a very comfortable and warm option for sleeping outdoors in colder temps. It would be great for side sleepers, or campers who want a pad light enough for backpacking without sacrificing comfort. I love that it comes with a stuff sack that inflates the pad easily. It packs up to a pretty compact package for being an insulated and thick sleeping pad. The material it’s made out of seems durable enough to withstand some abuse and shouldn’t be punctured easily. But if it does happen, it comes with a patch kit as well.
