I got a 4x from cabela's but it seemed like a 3x , I re-ordered a 5x and it is perfect . Ps it can be adjusted almost indefinately to as big as you want with the long straps provided I'd guess that a 7x could wear one . I'm from Canada and the cabala's price was $52US . by the time I got it with the exchange and border fees , shipping etc it was $104.00 exactly double .
