The Thermarest Prolite Small is the lightest and most compact self-inflating mattress of the brand. Thermarest invented the self-inflating camping mattress: over the years, the brand has perfected the art of making these high-performance camping and hiking mattresses.

Prolite is the basis of the Prolite range. It offers adventurers the lightest and most compact solution among self-inflating mattresses.
The mattress is 2.5 cm (1 inch) thick. It uses diagonally perforated foam to add warmth without excessive weight and has an R-value of 2.4 for three-season comfort.
This lightweight self-inflating mattress features our high-performance WingLock valve, which allows the mattress to inflate three times faster thanks to a larger opening and one-way inflation. Like all Therm-a-Rest mattresses, ProLite is locally produced to ensure quality and minimize environmental impact.
The mattress comes with a compact storage bag.

- Lightweight: the lightest self-inflating mattress available.
- Efficient heat: Diagonal cuts in the foam reduce volume and capture heat better than vertically cut foam.
- Small volume in the backpack: With its ultralight diagonally pre-cut foam and its tapered shape, the ProLite mattress fits easily in the backpack.
- Self-inflating: The foam core inflates automatically.
- A few more breaths are enough to achieve the desired degree of firmness.
WingLock Valve: Our intuitive and reliable valve maximizes airflow for easier inflation and faster deflation. Fins tilt to save your breath with non-return inflation.
- Comes with a storage bag.
