I have hunted out of alot of the pop-up blinds and own 4 diferent ones. They all have there faults but the one that seems to be the studiest and last the longest with out turning
PINK 
is the Double Bull. I actually got my Double Bull blind from an old lease of mine that someone had left behind. It was in sad shape because they had anchored it to a couple of trees in a big Mesquite flat and the thorns from the trees along with the high winds had done a number on it. I sowed up all the holes that I could and bought iron-on patches to close the holes where the material was actually missing. All this sounds pretty bad until you see this blind. Its in great shape now and is still working like a charm 4 years after all the repairs.
Its all in the quality of the material the stand is built out of. If you buy something that feels like a windbreaker jacket it will not last and it will probably turn Pink.
