Tent Extreme

Tent Extreme
I am looking for those tents that hang on vertical rock walls.?

every 1 has seen those extreme rock climbers that go u0p vertically and they camp out on the rock face. well i am looking for a tent like they use. it hangs on the rock face. a stiff bottom to it and all, i thought this might work somehow for camping up in a tree in bear country. ne way ne 1 know a web site that has extreme sports gear like this? thaks.
