tent suggestions for taller guys

The MSR Hubbas and the Big Agnes Seedhouse SLs are good up to that height, but not too much more.

There is also the TarpTent Double Rainbow or even the Squall.

I have no idea how much these items cost, so be wary of that. I am sure you could get them used or on sale.

The Sierra Designs Vapor Vapor Light 2 XL, available only through REI, at $350 is more than you want to spend, but if nothing else pops up I think it’s a contender.

It weights 3# 10oz, has a 93″x52″ floor, and 38″ of headroom.

My Double Rainbow fits me fine 6'3" 210lbs with my 65 pound long legged dog with room to spare for pack inside. Been great so far. It is in your price range also. Check the gear swap.

I don't know which part of the US you will be using the tent in Kevin, but I found the smaller version of the SD tent, the lightyear was great for solo use in the mountains. The inner of the clip flashlight is only 83" though, whereas in the lightyear it extends right to the front of the rainfly.

The Tarptent Squall2 may be worth a look if you would consider a single skin tent with built-in groundsheet and bug protection. http://www.tarptent.com/squall2.html
The height is good for tall people too, though I'm not sure where Henry found the midgets for the photo shoot. ;-)

Double Rainbow or Six Moon Designs Lunar Duo will give you plenty of room and save you some pounds.

I think the SD Clip Flashlight will be too short for you. I'm 6' even, and I feel cramped (length and width). One that might work for you is Marmot's Aura 2P. Mine weighs 4# 12 oz, tricked out with Easton Shorty stakes. It's not spacious, but their "bent knee" pole design maximizes the headroom, length, and width. I still prefer the Squall 2 though–lighter, more room.

I own the big Agnes sl 1, and I am 6 feet 4 inches. The tent is a great size however my problem is that even thought the tent is free standing it still requires stakes to keep its shape. I do not own a tarptent double rainbow however to save some weight and receive a larger interior of a tent that is what I would go with. So my advise is if you want to go ultralight in the future avoid the monetary pain of purchasing the big Agnes sl 1.

I second the Six Moon Designs Lunar Duo…

I'm 6'5" and 215. The tent is spacious, tall enough, and under three pounds. List price is $275 for a new one, not too far from your price range.
