Thermarest Trail Pro

The Trail Pro is the 4 seasons self-inflating mattress of Thermarest. It is the most comfortable and insulated model of the Thermarest range. It is 7.5 cm thick and has an insulation index (R-Value) of 4.4 with the new ASTM F3340-18 standard, allowing you to sleep with it, all year round.

Inside, the diagonal cut foam and air cushions trap air and ensure the mattress's "self-inflating" function, meaning that when you open the valve, the mattress gently fills with air.

It is equipped with Thermarest's latest valve. The WingLock valve allows you to inflate and deflate faster. It has a non-return valve that prevents air from escaping during inflation.
