the things i look for
material(quiet) usually the wind is blowing and a noisy blind is annoying to you and the animals
ease in setting up a good pop up is nice you dont spend alot of time putting it up or tearing it down
weight make it lite packing anything more than 10 pounds just sucks

(just a tip)
i try to set up my (double bull t2) ground blind at least 7 days before i use it unless i can hide it well in the trees on a trail the antelope and elk dont seem to mind it much but the mulies take a few days to get used to it
