A few breaths is all it takes.

Using physics (thanks, science!) Therm-a-Rest SpeedValve technology draws in surrounding air with your breath, filling up your sleeping pad 3x faster than conventional valves.

That means you get more time to sleep, and more energy for your next adventure.

When it's time to pack up, the auto-reverse valve deflates almost instantly. Just ​unbuckle the closure and roll up the mattress. Boom. Done.

About Therm-a-Rest

In 1971, three aerospace engineers found themselves needing a project. Tired of bad sleep on backpacking trips, they set to work designing a solution. Soon after, the Therm-a-Rest brand was born.

Seattle-based Therm-a-Rest started leading the industry after introducing the world's first self-inflating sleeping pad. They've continued to keep things exciting with innovations like insulation that zaps cold spots.

Wherever your adventures take you, Therm-a-Rest will make sure you'll always have a comfortable place to curl up. Their sleeping pads and insulation provide the rest you need through years and years of extreme adventure.
