I took this with me on my thruhike of the AT and while there are much lighter options, I came to love carrying the extra weight for the following reasons.
1) b/c it's freestanding, you can pitch it anywhere and move it to a flatter spot if you realize you're lying at an angle when you get in your bag to sleep. 2) It rains on the AT, ALOT! Especially in the Spring. You'll not want to spend a long time setting up your tent. I got so good at popping this thing up it took me only a few moments to where it would actually get rained on. My buddies went with the non freestanding Contrail Tarptent by Henry Shires which is fantastic but take a long time to set up. I was always in my tent drying off before them, so their bragging about how lightweight their tents were when I'd be dry in my tent which weighed literally a pound more, never got under my skin. 3) This puppy is durable. The materials are tough and very water resistant. The design of how the fly goes over the mesh is brilliant and I marveled at it every night before I'd go to bed. Because the clip design of the poles, the fly never touches the mesh which also means, no condensation whatsoever on the mesh, which means it never gets on you. Now, there is condensation on the fly, but you'll never notice it. This is not an opinion, it is a fact. You'll never notice it because of the geometry of the angles of this tent. If condensation becomes too much, the drops accumulate into beads and fall down to the perimeter of your tent. Not once did I wake up with a single drop of moisture on me or my gear at anytime. 4) This will stand up to high ridge exposure, snowstorms and snow stacking on the tent, 60 mph winds and extended driving rains. I more than once took a 0 day in this tent while the weather outside was just ridiculous. It would rain for 5 days straight without letting up and this tent took it in stride. I never got wet, the bathtub floors and seam sealing kept streams out of the bottom of my tent. I am 5'10" and my backpack and shoes fit inside the tent with me at my feet bc there is so much room in this thing lengthwise. My vestibule housed only my Crocs. I had a house out there on the AT and it was my Hubba. I swear by this thing. It is the only product I've ever reviewed which I wish I could give 6 stars. Get one now.

This tent makes me wish I hadn't bought a bivy. The extra room, privacy and protection is well worth an extra 2 pounds or so. Overall, a great solo shelter for light backpacking. The usual MSR bomber quality.

I love this tent. I am 6 foot tall and have a good 6 inches of room combined above my feet and a little room on both sides. It packs up small and is very light. I have never gotten wet with this tent and water doesn't even come through when you tough the rain fly. The vestibule is large enough for all my stuff and you can throw your shoes and stuff in the smaller one on the other side. One of the hooks ripped off on mine to attach the tent to the poles but besides that best tent i've ever had by far. Also I love being able to sit up in it and change.

This tent is fantastic! It goes up in a flash, literally 2 minutes. It breaks down just as easy AND packs back into it's bag with absolutely no effort.
The ventilation is great! Along that line of thought though this is a THREE season tent. Me and my buddy had the bright idea to push our gear for a low temperature test in preparation for an early spring Lake Superior trip and you WILL freeze your butt off in this tent in cooler weather. Of course it was supposed to only drop to 35F that night and it ended up dropping to 14F, lucky us!
Anyway, the quality of this tent is great. The stakes provided are tough enough to get in the ground even with a lot of gravel and stones in the ground without bending. The overall fit once up is great. If night temps drop significantly you may need to snug up the fly a little but it's not problematic.
The only caveat I would have is that the vestibule could be a little larger. This doesn't apply to me since I'm only 5'9" tall, but if you're over 6'2" tall you won't have much leeway when you lie down, especially if you bring any gear in with you. STILL, THIS A GREAT TENT!
