The tent is a classic double wall expedition tent. It has pretty steep walls (thanks to its bow-frame design) that gives it plenty of head-room and also steeply sloping side walls that maximise internal volume. This also helps to reduce condensation. It is very streamlined, so if pitched correctly facing into the wind it should be able to cope with quite serious storms by spilling wind over the top. It also has a strong construction and strong poles that should also allow it to shed high wind loads and snow.
I have fit two people very comfortably for nights on end, and three snugly. There are no holes, tears, leaks, or broken bits. Has kept my warm all the way down to about -35C.
