It's the tent brand of choice for many thru hikers — people who do the Appalachian, Pacific, or Continental Divide. It uses hiking poles as the main support structure and then you stake it into the ground.

I have a 2 man tent from Six Moon Designs. Very similar but the material isn't as fancy so it's heavier. I really like it and have fit two people, packs, and a large dog comfortably inside. It's very easy to set up. The only problem is since it's not freestanding, you need some good ground to stake in to. I tried setting up once on a small plateau in the Rockies and couldn't get the stakes to hold. Packed up and moved on. Kinda sucky at the end of a long day.
