I wear the scent blocker and to be honest i think it really works. I have had deer walk straight downwind from me and never smelt me. This has not been isolated instances either, this has happend several times when i was hunting on the ground. Now i do take showers in scentfree soap and use scent killer as well. I wear no cover scent at all and I never wear my scent blocker suits in, always carry them in. I sweat like the dickens when i wear it to the stand. Mine are rainproof soI dont have to worry about getting wet. They do cost alot I know,but I think there worth it.
