I bought an Avery Sport Utility Blind (SUB) in mossy oak duckblind camo for this years opener. I was hunting with two buddies using Avery X-landers, not sure what camo pattern. As "the Spank" said, stubble them up to match your surroundings and the camo pattern isn't important. The X-landers don't have as much interior space width-wise as the SUB (they are about the same length), but they do have a zipper to allow you to stuff gear under the backrest and have side pockets for ammo and calls. The width between the opened doors is similar. The SUB has a lot more room near the floor however and does allow you to store a hard shell gun case, lay out extra ammo, calls, snacks, coffee, water or whatever. My buddies were very happy with the price and performance of their X-landers and while not overly tall they are both pretty big guys. I'm quite happy with my SUB as well, it cost quite a bit more than their's but the extra room inside and the rigid doors are definite advantages in my opinion.
I would advise wearing full camo even though you are in a blind (including gloves and a facemask). If you go out to retrieve a bird and another flock comes in you can get down out of sight and at least your buddies can get a crack at them. Also close the doors on your blind whenever you leave it, all of ours are bright yellow inside, but even if your interior is camo coloured, the gear you have stored inside will be visible to incoming birds.
