Thermarest ProLite

The Therm-A-Rest ProLite� 4 is the lightest, most compressible four-season self-inflating mattress ever. This lightweight mattress is perfect for mountaineering, winter camping, backpacking and multi-day adventures. It is thick enough to use year round, making it a great choice for winter campers that don't want to carry a huge sleeping pad with them. The tapered and ergonomic design rolls up to the size of a bread loaf for easy carrying. Innovative materials and a new shape reduce overall weight by 25%. The super-grip bottom is made to "stick" to tent floor surfaces, so the pad will stay in place all night long.
