After hiking or trekking a handful of miles up a trail the last thing you want to do is sit on a soggy log or a frozen hunk of granite. The Therm-A-Rest Trail Seat provides rest stop warmth and extra padded comfort on lunch stops and water breaks. It's made with the same material and open-cell foam padding found in the Therm-A-Rest Expedition mattresses the warmest and most comfortable trail pad in the Trek and Travel collection.
