Is it needed? No, but I prefer to use it and take advantage of anyhelp I get in controling my scent. My scent control regimen includes many things, Scent Blocker included, but that is just a start. I wear it because I have seen favorable results many times while wearing it and I hunt in Camo clothes anyway so it might as well be Scent Blocker.

Scent Blocker's 08 line has some awesome selections thatI would be interested in even without the Scent blocker advantage.
