The Voss Diamond SI has the ideal shape to fit most tunnel tents. The tarp will protect against the elements, provide extra space, or create a small porch area outside the tent. With a very low pack size, the Voss Diamond Tarp is an easy addition to any pack. There are multiple attachment points; both along the edge and on the surface, allowing you to set up with the Nordisk Helmet Slide, poles or pegs – which are sold separately. The Voss Diamond comes with reflective guy ropes.
