I think most of the ads say "virtually eliminates odor," and the legal definition of "virtually" is "not." I'm sure saying it is all a scam is going too far, but I've had bucks approach me that I could have hit with a rock, and I've never used the fabric or sprays they sell. Holding still is more important than being scent-free, in my book.

Its impossible to remove all scent with a passive system (like your suit). Though it may be better than nothing, it won't let you get away with anything you can't do in normal hunting clothing.

i'm not saying scent lok does nothing... but it doesn't seem to do much.

You're not missing anything. It's a gimmick designed to scare hunters into buying more gear that they don't need. I've never used any kind of scent protection and every year I kill my deer and fill my freezer. Just tonight I shot a nice doe at about 15 yards with my bow and I wasn't wearing scent-lok clothing or any scent killing sprays. Great hunters have been playing the wind for thousands of years...there's something that can be said for that.

It is obviously possible to kill deer in any outfit, scentlok is designed to lower the scent put off by a hunter but it can not eliminate all smells. However it is an excellent product when used properly and in conjunction with other scent blockers or cover scents. For a hunter who is targeting the incredibly savvy more mature bucks it is essential to do everything you can to try and keep from being detected.
