Excellent comfort and isolation from the ground with a super-thick build.

Expensive and only moderately insulated.

For those who sleep on their sides and who tend to move around in the night Sea to Summit’s Ether Light XT Insulated is the ideal choice. With an impressive 4 inches of padding off the ground and a hefty 4 inches of padding, the Ether is the largest mattress on the list, and weighs 1 pounds 1.3 pounds and 1.3 ounces. Other noteworthy characteristics include Sea To Summit’s unique air Sprung Cells with the 3.2 R-value, which should be sufficient for most shoulder and summer backpacking trips (it was a success at nights when temperatures were with temperatures in the mid 20s Fahrenheit) as well as an insulated double pump and stuff sack that allows to ensure quick and easy inflation. In all with the Ether is among top-of-the line pads available on the market.

Although admittedly, such a large pad is not necessary for a lot of backpackers, not just those who sleep on their backs, as well as larger humans generally (we’ve observed it to be the 2.5-in. Therm-a-Rest NeoAirs suffice in the majority of cases). Additionally, the additional cushioning Sea to Summit provides Sea to Summit offers comes with an increase in weight. The Ether Light XT Insulated is more than 5 pounds more heavy than the Light XLite. In addition, if weight isn’t an issue you should check Nemo’s top-of-the-line Quasar 3D below, which has a soft-touch top as well as a rectangular shape with a slightly higher R-value, 3.5. Overall for those who want to create as much space as they can between themselves and their ground The Ether is a tough one to beat. Sea to Summit also has Ether Light XT Extreme ($199). Ether Light XT Extreme ($199 1 lb. 9.4 oz. ) that adds Thermolite insulation for the R value of 6.2 in addition to the lighter, more summer-oriented Ether LightXT Air ($189, 13.8 oz. ).
