User Review: NEMO Tenshi
I just got back from a successful climb on the West Ridge of Mt Hunter in Alaska. This route was beefy. I used the Tenshi during the 6 days on route.
It's a great tent. Everything you want from a single wall tent for alpine pursuits. It vents well, is strong, and light weight. There are lighter tents out there, but if the weather craps out, you will want something this strong. The footprint is big enough to get two people and their gear, but not so big that you have to dig a huge snow platform.
I plan on taking it anytime I'm going big in Alaska.
