It's because they are 2 to 3 times the blind that the others are!!! As mentioned above, other blinds are made out of MUCH cheaper material. The DB blinds feature a much heavier canvas type material that is going to last MUCH longer! I have hunted out of different brands and they don't even begin to compare in construction quality and overall design features. I have always loved my T5 but I just picked up a new Matrix this past week and it is the cats meow in ground blinds! I'll be "testing" it out in the Turkey woods this weekend! You can spend the extra money NOW for a Doouble Bull OR you can waste money buying a couple of cheap blinds and THEN have to go spend that money on a Double Bull, your choice.
