The Sea to Summit Nylon Tarp Poncho is a 4-in-1 raincoat, backpack cover, groundsheet, and shelter. Durable and compact, it's multi-use gear that no adventurer should be without. Made from waterproof 70D nylon, the seams are double stitched and tape sealed. The sides snap together for rain protection when used as a poncho, and the three-panel peaked hood provides additional coverage from the elements. A large backpack can be worn underneath, and the tarp can easily become a shelter with the guy line attachment points. The Sea to Summit Nylon Tarp Poncho measures 57 x 104 inches, packs down to 3.5 x 7.5 inches in the included stuff sack, and weighs 14 ounces. Sea to Summit products are guaranteed against defects in materials or workmanship for the lifetime of the product.
