its just more little thing that might mean the difference between getting a deer and not getting a deer. I think its worth every penny. I was not winded once this year and the 9 point that i shot came from directly down wind of me. I also hunt high, rubber boots, sprays and scent wafers too. sometimes they do make you sweat so most of the time i walk into the woods and when i get about 100-200 yards from my stand, i suit up and spray down and take my time. i am starting on my second suit and i think they are worth every penny
