The Thermarest Prolite Apex is a lightweight and warm self inflating mattress. It offers plenty of comfort, even in cooler conditions, without taking up a huge amount of space in your pack. As a self inflating mat it uses its expanding foam core to fill with air and then requires just a few breaths to reach the required firmness.
Thermarest's StrataCore Construction gives the best warmth to weight ratio in any self inflating mattress. It does this by using a continuous layer of foam between ridges of air and foam. This technology gives the Prolite Apex an R-Value of 4.0 making it suitable for 4 season use.
