The more you sweat, the more you will smell. The scent lock clothes do help to hold and negatein the smell quite a bit.
I see alot of hunters using the scent lock clothes and neglecting to cover their face and worse, their heads.

I use a scent lok hood,scent lokgloves (just because they fitwell) anduse the scent free soap, shampoo and deodorant. I wash all my hunting clothes, including socks and underwear in scent free laundry soap.
Lastly I dry my clothes with dryer sheets that have a natural earth scent. I also store my clothes in scent lok bags.

Ihad two deer come directly into my ladder stand with the wind NOT inmy favor and both of them never knew I was there.

The scent lok clothes probably work very well, I just don't see the point in spending that much dough when I can get the same results for a whole lot less. I use the hood because I sweat like a slave, no matter the weather!
