The Thermarest ProLite™ is one the lightest, most compact 3-season self-inflating mattress on the market.

Thermarest uses die-cut foam to eliminate excess weight and rolls up ultra-compact. Grip-Dot bottom keeps mattress from slipping.  Lightweight top fabric provides a soft, low-slip sleep surface. Streamlined shape saves weight and rolls up super small.

Now lighter and more compact than the previous version, weight is the only thing you’ll find missing. Innovative materials create a mattress that’s 20% lighter.

Engineered for 3-season backpacking, mountaineering, and bike and boat touring.
