Expedition. Ready. 

Stronger, more stable, and built to withstand the harshest of conditions, the Mad House series of shelters are much more than standard tents. They are the Everest base camp dining rooms, buttoned up Black Rock City roosts, and Vedauwoo wind refuges. The Mad House series is our biggest mountaineering design. Try one as an all-season condo with plenty of space to stretch out and relax on acclimation days, or as a place to serve pancakes to the entire summit team
