The Integral Designs Siltarp is an extremely versatile tarp made from ultra light waterproof nylon. Silicon impregnation seals out water and keeps the Siltarp's ripstop fabric at an ethereal 1.35oz per square yard, yet it remains incredibly strong and resilient. Functioning as bare-bones overhead shelter for use with a bivy sack, or as a cooking and gear storage awning, the Siltarp can be set up on hiking poles, slung between trees or attached to a tent or hooped bivy. 16 webbing tie loops sewn on the corners and edges, and one reinforced loop in the center facilitate a number of different set ups. Because it has no seams, it requires no seam sealing and is ready to go out of the box.
