This versatile mat provides durable, waterproof insulation for limitless
applications. Use it as a ground cover for your tent, a picnic mat on snowshoe
trips, or as an emergency sleeping mattress if yours suffers a puncture. The
nylon top is soft and comfortable to the touch and is large enough for two
adults to spread out comfortably. The EVA foam on the under side wards off
cold, water and sharp stones.
