I broke down and bought a Supprescent suit half way through our season. Before I bought it this year, I got busted, and snorted at, numerous times. After I started wearing the Supprescent system, I was never snorted at. I had deer downwind of me on several occasions. A couple deer did get a little nervous, but they never snorted or took off running. They cautiously walked away. I was surprisingly impressed with how well the clothing actually worked. I was as big of a skeptic as anyone, but so far I'm really impressed.

Like others have said, it's not a "cure all," but IMO, it certainly helps.
