Most emergency shelters are just that, designed to be used once or maybe twice and then discarded. The SOL Sport Utility blanket is different. Durable enough to be used as an emergency shelter one day and as a picnic blanket the next, it is up to any task. Use it to haul heavy loads, as a ground tarp or tent floor, rig it as a shelter or cover your gear. Reflects 95% of body heat back to you. Weighs only 11.3 ounces. 5'x7'.
