This is an exceedingly well made, well designed tent that offers a bit of comfort in your pack without weighing it down. Two storm worthy bivy sacks weigh as much as this tent sans vestible, and the tent is much more comfortable. Set up is simple.
I'm 6'3" tall, and bought this tent understanding that I am too long for it. Laying parallel in the tent, I can almost stretch out if I am willing to put my face in the fabric. It is still more comfortable than a bivy sack and much faster than digging a cave.
Condensation is considerable, even with good venting.
Friends have used this tent on Denali and Blackburn and put it through some serious tests.
