I agree w/ Gator. I do a lot of deer hunting (Pa, Iowa, Kansas, Ohio) and in my opinion a carbon suit alone will not help much with scent control. I am a fanatic when it comes to scent control and I personally do not use a carbon suit. I wash ALL of my clothes in unscented laundry detergent including my underware, hat, socks, gloves, backpack etc. I also keep my outer hunting clothes outside or in a scent proof container if they go inside. Knee high rubber boots are a must. Before I take to the field, I take a shower w/ scent free soap followed up with scent free deoderant. I put my outer hunting clothes on when I get to my hunting spot not before. I then spray myself down with a scent killing spray. One very important thing to remember is to play the wind when chosing your hunting spot each time you go hunting. I don't think you can eliminate scent but you can minimize it.
