The EV3 Tent by Mountain Hardwear is designed by the highly acclaimed mountaineer Ed Visteurs. His input from his years of mountaineering experience helped to build a compact, light, strong, three person tent. This is a tent constructed primarily for the rigors of high altitude expeditions with its trim design that fits on ledges and its easy clip set-up can withstand high wind pitches with no problem. Made with VX02 fabric, a lightweight, strong, non stretch laminate that stabilizes and strengthens when put up and the Atlas Scandium XL poles add incredible stability while still shaving weight. Frost management is maintained with its interior zip and built in ventilation while the vestibule provides excellent protection from harsh elements. This is a single wall tent, which means the fly and body are one in the same.
