Eureka! Wabakimi

Have yet to use this tent in serious conditions, but so far, it's been pretty good. mild rain did not get through. What got us wet, however, was condensation building up on top of the tent (under the fly), which ran down to the mesh and came neatly through where the mesh met the nylon fabric. Right at your forehead!
not so simple to set up (sleeves), but simple enough with two people. gigantic vestibule (nearly too big), and incredible interior space. Not enough ventilation/observation mesh for my liking, but there is some.
