WickiUp 4 set including full size room. Ultra Lightweight tent system, which offers the best space-to-weight ratio. The WickiUp series has been constructed from GorLyn 20 fabric using high-tenacity nylon 6.6, with a yarn thickness of 20 denier, which has a higher tensile strength than regular and most used nylon in tent construction. The pyramid style design with one DAC center pole cuts weight in a big way. It offers extreme stability in bad weather conditions. The fly sheet can be used as independent shelter and the optional inner tent can be used without the fly sheet.
