## Description

One of the lightest and most packable self-inflating sleeping pads, offering excellent insulation performance. The Therm-a-Rest ProLite™ Apex™ stands out with a comfortable thickness of 5 cm and a high thermal resistance of R= 3,8.

## Features you will appreciate.

Light and compact self-inflating sleeping pad with a thermal resistance of R=3.8.

## Top-quality self-inflating sleeping pad

- **StrataCore™ construction:** a thoughtful design with the best weight-to-thermal resistance ratio of all self-inflating sleeping pads. The sculpted foam, whose construction alternates layers of foam and air chambers, creates a balanced ratio of thermal insulation, volume, and weight.
- **Ultralight and comfortable:** self-inflating sleeping pad with great weight and high thermal resistance **R = 3,8**, sufficient **for three-season** adventures.
- **Durable:** the sleeping pad is constructed from 50D polyester material.
- **Robust self-inflating foam:** after opening the valve, the expanding foam core inflates. The sleeping pad only needs to be topped off with a few breaths to the desired firmness.
- The package includes a **transport compression bag**.

## Variants

**The Regular size is 183 cm long, 51 cm wide, and weighs 620 grams.** When packed, it has the shape of a cylinder measuring 28 x 17 cm.

**The Regular Wide size is 183 cm long, 64 cm wide, and weighs 790 grams.** When packed, it has a cylindrical shape with dimensions of 33 x 18 cm.

**The Large size is 196 cm long, 64 cm wide, and weighs 850 grams.** When packed, it has the shape of a cylinder measuring 33 x 18 cm.

## New WingLock™ valve

After more than 100 prototypes and 500 nights of field testing, the **new valve called WingLock™** is finally here and is better in just about everything!

Compared to the previous model, you should be able to **inflate your sleeping pad up to 3x faster**. The valve is **wider and one-way**, so air won't escape while inflating. By turning the "wings" on the sides of the valve, you can easily and quickly deflate the pad. In case of damage, you can easily replace the valve.
