I am 6' 4" tall and I have no problem using the Ameristep Doghouse blind. Heck, I have even hunted in it with one or two other hunters though 3 is definitely crowded.

It is quiet, easy to use, very affective, lightweight, durable and the best part is the price. Cabelas has them for $70 in Tangle camo or $80 in Breakup.
