This self-inflating mattress is Thermarest's standard 1.5" thickness so you get a comfortable sleep. The semi-rectangular shape increases your sleeping area and makes the mat easy to pair with another. The interior has die-cut foam to reduce bulk and weight and the mat rolls up into a compact stuff sack (included). This updated Trail Lite has the new WingLock Valve which maximizes air flow and toggles for one-way inflation, making it easy and quick to set up.
