The ZUNI 4 is part of the GRAND CANYON shelter series, which includes tarps of different sizes and shapes. They serve the traveler as a rain or sun roof, as a windbreak or simply as an emergency bivouac for an outdoor camp. But the tarps also serve well in the garden or on the beach. The circumstances are always different and the possible uses are diverse. The robust polyester fabric is waterproof coated and allows UV protection of 50+.
