RE: scent control?
I've used Supprescent for the past couple years and do believe it helps. Key word is "helps." You still need to use scent free soaps, spray down with scent killer, play the wind, etc.in order to be as scent free as possible. With that said, I never go into the woods without my Supprescent headcover, jacket, pants, and gloves. I truly believe it has helped me see more deer.
As for the price argument, yes if you buy scent control clothing from a retail store you will pay top dollar. I've been buying my Supprescent clothing on eBay lately. I got a new jacket and pant set for $75.
