The Marmot Thor 3-Person 4-Season Tent has an intelligent six-pole design that wards of strong winds and snowstorms during the most intentse high-mountain expeditions. Designed specifically for alpine climbing and mountaineering, the Thor Tent stands strong in the most intense mountain ranges of the world. Dual doors and vestibules allow quick and easy entry for all three partners, and provide a place to store all your wet and extra gear. The unique Knee Pole System steepens the walls and increases useable interior space which makes all the difference when you are riding out an extended storm.
