Designed to Ed Viesturs'specifications for a compact, light, strong, two-person tent, the EV2 is purposefully designed for the rigors of high altitude expeditions. EV2s trim design fits on ledges, and its clip set-up aids high-wind pitches. TX07 PU fabric - a lightweight, strong, non-stretch laminate - stabilizes and strengthens when pitched, and Atlas Scandium XL poles add sturdiness while shaving weight. Interior zip and built in ventilation help frost management while integrated vestibule provides protection from the elements.
