No subject to promotional offersThe Ether Light XT Insulated is an insulating mattress from the brand Sea To Summit.
It features technology Air Sprung Cell™ that provides air cells with greater capacity thanks to TPU mesh partitions that connect the fabric on the sleeper side to the fabric on the floor side. This design allows the two sides of the mattress to be spread further apart, creating larger air pockets when inflated, while using less fabric.
Featuring an R-Value of 3.2, this is a 3-season mattress that will provide you with a sufficient level of insulation to accompany you throughout the year. To achieve this, Insulation is Thermolite combined with .Exkin Platinium The Thermolite is present in the cells and will help limit heat loss, while l'Exkin Platinium will reflect your body heat for optimal insulation.
All mats Sea To Summit come with a storage bag that has an integrated pump Airstream. There is also a repair kit containing six self-adhesive puncture bearing patches and a replacement check valve to ensure long-lasting use of the product.

| INTEGRATED AIRSTREAM | TheAirstream Pumpsack is the high-volume mattress pump that Sea to Summit we have now integrated into the storage bag of each mattress Air Sprung Cell. The clever design opens at one end to store the air mattress, and the other end unfolds to become the integrated pump. TheAirstream Pumpsack can be inflated with a single breath, and it only takes two or three cycles to fill our mats. Not only is it quicker than inflating by mouth, but there is little condensation in the mat and there is no dizziness from inflating the mat directly by mouth. |
| ASTM F3340-18 R-VALUE TESTING | Since January 2020, we have been using the industry standard ASTM F3340-18 test to provide the R-values of our mats. |
| ETHER LIGHT XT AIR SPRUNG CELLS | Les Air Sprung Cells are the basic technology used in mattresses Sea to Summit , which is why you will sleep more comfortably on a mattress Sea to Summit than on a conventional air mattress. Inspired by the springs in a modern pocket spring mattress, dozens of interconnected chambers (called Air Sprung Cells) perfectly support your weight and adapt to the contours of your body. The range Ether Light uses TPU loops to connect the upper and lower welds. This creates a thick cell, giving you a plush sleeping experience without compromising the comfort of the Air Sprung cells Sea to Summit. |
| THERMOLITE® | Our insulated air mattress mats use insulation THERMOLITE®designed to provide excellent lightweight warmth and superior durability. The insulation THERMOLITE® rises inside the spring cells to prevent convective heat loss from your warm body to the cold floor. |
