Thermarest Prolite 3 Regular: The lightest, compact, three-season self-inflating mat.

The Prolite 3 is a thin mat for three-season use and maximum compressibility, and features a sticky-dot surface that ensures you and your mattress don't slip around the place.

The die-cut foam allows for smallest roll size ever at only 10cm in diameter meaning you can fit it in any 35L rucksack still having space for the rest of your weekend gear.

Great for mountaineering, winter camping, backpacking and multi-day adventures.
