Unlike other ultralight sleeping pads, this one is nearly double the thickness – 10 cm. This new model of inflatable sleeping pad from Sea To Summit is also lighter, more compact when packed, and has a higher R value. ## What makes this product special? Comfortable and packable three-season inflatable sleeping pad. inflatable sleeping pad, three-season, 30D/40D nylon fabric, ThermalCore insulation, Air Sprung Cell™ air cells, XPRESS multi-function valve, PillowLock™ system for attaching a pillow, Airstream™ Pumpsack – pump sack and stuff sack in one, repair kit included ## Material and construction The STS Ether Light XR Insulated inflatable sleeping pad builds on the previous [Ether Light XT Insulated](/p/sea-to-summit-ether-light-xt-insulated) model, but thanks to the improved design, it's even **lighter** and **more** **packable**. The sleeping pad comes with the new **multifunctional** **XPRESS** **valve**, which makes inflating, deflating, and pressure adjustment quicker and easier than before. The **Air Sprung Cell™ technology** (air-sprung cells) gives you awesome body support while you sleep – **each cell acts independently** and doesn’t affect the others (so when you toss and turn, you don't feel like you're "floating"). The sleeping pad is constructed from **30D/40D high-strength nylon** that doesn’t crinkle. Inside the sleeping pad, there’s **ThermalCore insulation** with a single layer of TRM, which effectively reflects heat back to you. This layer reduces air movement inside the pad, and smaller cutouts compared to previous models further minimize this effect. The result is an increase in R value while also lowering the weight and packed volume. Plus, the sleeping pad has improved seam strength for greater durability and longer life. The Ether Light XR Insulated stands out mainly with its **thickness of 10 cm**, so it reliably evens out any surface irregularities. - **Regular** size is 55 cm wide and 183 cm long. Packed, it has a cylindrical shape with a diameter of 11 cm and a height of 20,5 cm. It weighs **470 grams**. - **Large** size is 64 cm wide and 198 cm long. When packed, it’s cylindrical with a diameter of 11,5 cm and a height of 24 cm. It weighs **605** **grams**. ## Specifications and sccessories The sleeping pad has an **R-value of R=4,1**, making it suitable for **use from spring to autumn**. Tough folks can even handle mild winter with it. Sea To Summit sleeping pads are measured according to the ASTM F3340 standard. If another manufacturer uses this standard, you can easily compare sleeping pads across brands. The sleeping pad features a unique **PillowLock™ system** – self-adhesive Velcro that lets you easily and securely attach any Sea To Summit pillow to the pad so it won’t slip away. You'll get the **Airstream™ Pumpsack** with the sleeping pad – a small storage stuff sack and a pump sack in one (55 g for the Regular version, 60 g for the Large version) and a repair kit. ## Specs - Color: Grey - Sleeping pad size: Large, Regular Rectangular Wide, Regular - Sleeping pad type: Inflatable - R-value: 4.1 - Season: 3-season - Insulation type: ThermalCore - Material: 40D nylon, 30D nylon - Thickness: 10 cm - Weight: 665 g - Length: 183 cm - Width: 64 cm - Height: 10 cm - Woocommerce product id: 137348 - Brand: Sea To Summit ## Variants - Sea To Summit Ether Light XR Insulated - Regular Rectangular Wide · SKU ASL051152-291703 · EAN 9327868162581 · €206.60 · In stock · Regular Rectangular Wide, Grey - Sea To Summit Ether Light XR Insulated - Large · SKU ASL051152-061704 · EAN 9327868162598 · €210.90 · In stock · Large, Grey - Sea To Summit Ether Light XR Insulated - Regular · SKU ASL051152-051702 · EAN 9327868162574 · €189.70 · Out of stock · Regular, Grey ## Related - [Sea To Summit Ether Light XT Extreme Insulated](/p/sea-to-summit-etherlight-xt-extreme-insulated.md) - [NEMO Switchback](/p/nemo-switchback.md) - [Therm-a-Rest NeoAir XLite NXT Max](/p/therm-a-rest-neoair-xlite-nxt-max.md) - [Tyvek 75x230 cm (for 1 person)](/p/tyvek-groundsheet-230-x-75-cm.md) - [Sea To Summit Women's Ether Light XT Extreme Insulated](/p/sea-to-summit-womens-ether-light-xt-extreme-insulated.md) - [Gramino Ultralight Sit Pad](/p/gramino-ultralight-sit-pad.md) - [Therm-a-Rest NeoAir XTherm NXT](/p/therm-a-rest-neoair-xtherm-nxt.md) - [Sea To Summit Utensil & Peg Bag](/p/sea-to-summit-utensil-peg-bag.md) ## Shipping and returns - [Shipping and payment](/shipping-payment) - [Returns](/return-order) ## Images - ![Sea To Summit Ether Light XR Insulated](https://media.gramino.com/medusa/90142c7b2653c19b0a7f5a7407738288-01KWHVRK2A7S21C8K2FJ40NNM4.webp) - ![Sea To Summit Ether Light XR Insulated](https://media.gramino.com/medusa/c5d7722e57c5772748b370c93e7dc75a-01KWHVRK2NMCDEWAN2SXQT4BAN.webp) - ![Sea To Summit Ether Light XR Insulated](https://media.gramino.com/medusa/8b09f9b4270f580e40d4640377d3893a-01KWHVRK2913DGF3YVH7MV122J.webp) - ![Sea To Summit Ether Light XR Insulated](https://media.gramino.com/medusa/47523f57354a5c6e67c932bbb9a35622-01KWHVRK2VZA65HQ3EF0NPGR18.webp) - ![Sea To Summit Ether Light XR Insulated](https://media.gramino.com/medusa/3d6e0f9b0961989d789e8fb084fc8dba-01KWHVRK9FHGWMH43PS49ASQZB.webp) - ![Sea To Summit Ether Light XR Insulated](https://media.gramino.com/medusa/20b169a89b9c4009a9275d1477452d7d-01KWHVRKA1S3DT434PV7WRN12F.webp) - ![Sea To Summit Ether Light XR Insulated](https://media.gramino.com/medusa/ef80444c12afb4a35b9cfa598b3a8058-01KWHVRKA73JD76S6VGGT0PABS.webp) - ![Sea To Summit Ether Light XR Insulated](https://media.gramino.com/medusa/f57fd08b4f1a816489f24091a56c43ef-01KWHVRK9WADZQF4TWTQTAD5VQ.webp) ## Identifiers - SKU: ASL051152-291703 - EAN: 9327868162581 - Handle: sea-to-summit-ether-light-xr-insulated - Brand: Sea To Summit This product is also available as [HTML](/p/sea-to-summit-ether-light-xr-insulated).
