## Description

A thoughtfully designed three-season inflatable sleeping pad, on which you will sleep like at home. Compared to other ultralight inflatable sleeping pads, it has almost double the thickness – 10 cm. However, this is not reflected in its weight and packability.

## This could come in handy.

Super comfortable and thoughtfully designed three-season inflatable sleeping pad.

inflatable sleeping pad, three-season, 30D/40D nylon fabric, Exkin Platinum® aluminum insulation layer, THERMOLITE® synthetic insulation layer, internal antibacterial treatment, Air Sprung Cell™ air cells, multi-function valve, PillowLock™ system for attaching a pillow, 2-in-1 stuff sack and pump sack, and repair kit included

## 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.

Inside the sleeping pad, there is a **thin layer of Exkin Platinum® aluminum** that reflects radiant heat back to the user. In the chambers of the sleeping pad, we then find **THERMOLITE® synthetic insulation**, which prevents loss of body heat to the cold ground.

The Ether Light XT™ Insulated stands out primarily for its **thickness of 10 cm**, so it reliably compensates for any unevenness of the surface.

- **The small size is 55 cm wide and 168 cm long.** When packed, it has the shape of a cylinder with a diameter of 11 cm and a height of 24 cm. It weighs 470 grams.
- **The regular size is 55 cm wide and 183 cm long.** When packed, it has a cylindrical shape with a diameter of 12 cm and a height of 24 cm. It weighs 490 grams.
- **The large size is 64 cm wide and 198 cm long.** When packed, it has a cylindrical shape with a diameter of 13 cm and a height of 28 cm. It weighs 625 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 the orange spot in the middle will release the air.

### Deflate

Opening the second section will release the air from the sleeping pad in a few seconds.

## Specifications and accessories

The sleeping pad has a **thermal resistance value of R = 3,2** and is suitable for use **from spring to autumn**. Sea To Summit sleeping pads are measured according to the ASTM F3340-18 standard. If another manufacturer also 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.

You will receive a **small storage bag (stuff sack) and a pump sack in one** (40 g), as well as a **repair kit** with the sleeping pad.
