The Siltarp3 is a 10 ft x 12 ft rectangular tarp made from ultralight waterproof nylon. Designed for adventure racers that need an extremely lightweight and versatile tarp to protect them from the elements, the Siltarp 3 will protect 4 - 5 in 120sq ft. (11 sq m) of space. It can be setup as a semi-enclosed, modified, A-frame or be a wind/rain shelter for larger group. The possibilities are limitless for the different ways that you can setup a Siltarp3. The 30 denier parachute ripstop nylon with silicon impregnation weighs only 1.35 oz per sq yard. It is incredibly strong and resilient. The Siltarp3 is designed for groups looking for a lightweight shelter. At 20 oz (560g) it is light enough to take on all trips. The Siltarp3 has a seam down the centre of the 12 ft length, which provides extra strength but does require manual sealing (Silnet seam sealant provided). There is 1 lightweight nylon tie loop sewn to a reinforced center patch and there are 20 lightweight nylon webbing loops sewn to the corners and at 2 ft intervals along the 12 ft sides and 2'6" intervals along the 10 ft sides. These loops facilitate a variety of setups on trekking poles, paddles, avalanche probes or off trees.
