You should always hunt the wind anyway. Scent Blocker clothing just gives you more of an advantage. I am a believer, i had my whole suit on and had 8 does standing 40 yds away from me downwind, the sat there for about 20 mins eating and as soon as they wernt watching i took off the headnet and about 1 min. later the flags went up and the started snorting and took off. You can say what you want but if you try one you will never go into the woods without it.
