Thermarest Trail Lite Large

The Therm-a-Rest Trail Lite Large is a self-inflating sleeping pad designed for backpackers who want a bit more room without carrying extra weight. Its larger footprint accommodates taller campers, and the foam core inflates itself as soon as you open the valve, so you can settle in quickly after a long day on the trail.

With a thickness of up to 3.8 cm, this pad eases pressure under your hips and shoulders while still packing down to a manageable size. The extra length helps you stretch out fully, reducing the tendency to curl up, and the self-inflating design cuts setup time—just open the valve and let the foam do its work.

An open-cell foam core is sealed inside a rugged shell. When you crack open the valve, the foam naturally expands and draws in air, filling the pad without a pump. Add a few breaths if you like a firmer feel, then close the valve to lock in the air and maintain consistent support through the night.
