Well there are a lot of options, depending on how much you want to spend.
Right now would be a good time to check out Cabela's, Bass Pro, or your local sporting goods stores for a good bargain on clearance since season is mostly over now for most areas.
I have a Primos vest that is light with straps and has plenty of pockets for what I carry. It has mesh back and plenty cool. I want to get one with a little more cushioning on it, that is my only complaint.
Shop around now and I bet you can find one at a good price
