The Sea To Summit Ether Light XT Extreme Insulated stands out with a thickness of 10 cm, a versatile valve, and a reliable construction. ## You might like this. Extremely comfortable and thoughtfully designed winter inflatable sleeping pad. ## Construction The Air Sprung Cell™ technology provides great body support while sleeping – **each cell behaves independently** and does not affect one another (you don’t feel like you’re "floating" when tossing and turning). The sleeping pad is constructed from **30D/40D high-strength nylon** that is quiet. To prevent mold growth inside the pad from the moisture in exhaled air, it is treated with an **antibacterial coating** on the inner side. The package also includes a pump sack for easy inflation. In the chambers of the sleeping pad, we find a **double layer of THERMOLITE® synthetic insulation**, which prevents the loss of body heat to the freezing ground. Ether Light XT™ Insulated stands out primarily for its **thickness of 10 cm**, so it reliably compensates for any unevenness of the surface. - **The regular size is 55 cm wide and 183 cm long.** When packed, it is cylindrical with a diameter of 17,5 cm and a height of 24 cm. It weighs 720 grams. - **The large size is 64 cm wide and 198 cm long.** When packed, it has a cylindrical shape with a diameter of 18,5 cm and a height of 28 cm. It weighs 950 grams. ### Multifunctional valve Handling it is a breeze. Quick inflation and deflation, and the ability to adjust the firmness of the sleeping pad. ### Inflate By opening the first section, you can inflate the sleeping pad and the air does not escape. Pressing on the orange dot in the middle will release the air. ### Deflate Opening the second section will release air from the sleeping pad in a few seconds. ## Specifications and accessories The sleeping pad has a **thermal resistance value R = 6,2**, which is reliably sufficient even **for winter conditions**. Sea To Summit sleeping pads are tested according to the ASTM F3340-18 standard. If another manufacturer uses this standard, you can easily compare sleeping pads across brands. The sleeping pad features the unique **PillowLock™ system**, which allows you to easily and securely attach any Sea To Summit pillow to the sleeping pad so that it doesn't slip away. With the sleeping pad, you will receive a **small storage bag** (stuff sack) **and a pump sack in one** (62 g) and a **repair kit**. ## Specs - Color: Black - Sleeping pad size: Large, Regular - Sleeping pad type: Inflatable - R-value: 6.2 - Season: 4-season - Material: 30D nylon, 40D nylon - Material composition: Nylon - Thickness: 10 cm - Weight: 950 g - Length: 198 cm - Width: 64 cm - Height: 10 cm - Woocommerce product id: 21975 - Brand: Sea To Summit ## Variants - Sea To Summit Ether Light XT Extreme Insulated - Large · SKU AMELXTEXML · EAN 9327868139415 · €237.80 · Out of stock · Black, Large - Sea To Summit Ether Light XT Extreme Insulated - Regular · SKU AMELXTEXMR · EAN 9327868139408 · €253.50 · Out of stock · Black, Regular ## Related - [NEMO Tensor Extreme Conditions](/p/nemo-tensor-extreme-conditions.md) - [Flextail ZERO Pump 2](/p/flextail-zero-pump-2.md) - [Therm-a-Rest NeoAir XLite NXT Max](/p/therm-a-rest-neoair-xlite-nxt-max.md) - [Sea To Summit 70D Nylon Tarp Poncho](/p/sea-to-summit-70d-nylon-tarp-poncho.md) - [Therm-a-Rest NeoAir XTherm NXT](/p/therm-a-rest-neoair-xtherm-nxt.md) - [Sea To Summit eVac Compression Dry Bag UL](/p/sea-to-summit-evac-compression-dry-bag-ul.md) - [Therm-a-Rest NeoAir XTherm NXT Max](/p/therm-a-rest-neoair-xtherm-nxt-max.md) - [Sea To Summit Mat Coupler Kit Loops](/p/sea-to-summit-mat-coupler-kit-loops.md) ## Shipping and returns - [Shipping and payment](/shipping-payment) - [Returns](/return-order) ## Images - ![Sea To Summit Ether Light XT Extreme Insulated](https://media.gramino.com/medusa/d6a24b3b5b112bc3109fe5dfa22eaadf-01KWHVKD8XXWR63ERZSEHYHYDE.jpg) - ![Sea To Summit Ether Light XT Extreme Insulated](https://media.gramino.com/medusa/b97a990ff227fb264319e0ee5846a14f-01KWHVKDAZY85C8G880HN25E92.jpg) - ![Sea To Summit Ether Light XT Extreme Insulated](https://media.gramino.com/medusa/00a1ba3d60f3332a2fdb78bc751a84cc-01KWHVKDBSQDEHP3GP1YH0XY1B.jpg) - ![Sea To Summit Ether Light XT Extreme Insulated](https://media.gramino.com/medusa/110cdc3dab753547c4c5ea639b1ae164-01KWHVKDDPY8CC2XP6Y1AXEVAC.jpg) - ![Sea To Summit Ether Light XT Extreme Insulated](https://media.gramino.com/medusa/65dea656fcc515519a6efe1c248827a8-01KWHVKDD73PFNWETF8P5JNDM6.jpg) - ![Sea To Summit Ether Light XT Extreme Insulated](https://media.gramino.com/medusa/74b0baba919de8e2171f4748919635bf-01KWHVKDFZJBE12Q3059VJ9BYT.jpg) - ![Sea To Summit Ether Light XT Extreme Insulated](https://media.gramino.com/medusa/a3cc6d0e14b9d2bc9d4826c7f31ddcfc-01KWHVKDFJF0305V3Q4NVK2N7M.jpg) - ![Sea To Summit Ether Light XT Extreme Insulated](https://media.gramino.com/medusa/bb44651349d452cf6fce2724110f3286-01KWHVKDGPWZR3H59DGYRGW4MA.jpg) ## Identifiers - SKU: AMELXTEXML - EAN: 9327868139415 - Handle: sea-to-summit-etherlight-xt-extreme-insulated - Brand: Sea To Summit This product is also available as [HTML](/p/sea-to-summit-etherlight-xt-extreme-insulated).
