I have used scent-lok in combination with sprays and such. I agree with several that have posted that scent-lok with only somewhat reduce your scent, not eliminate it. Where I hunt in CT, we have a healthy hiking population so if I can get deer to smell something, but not be sure what it is, that is an advantage. I had that very experience last season. I had on a full scent-loking outfit with a hat, all sprayed down, and when the spike walk into the wind carrying my scent, he stopped, sniffed, looked around and cautiously continued on. He smelled something (me) he just wasn't sure what that something was. IMHO, a good shower, air dried clothes outside, spray, hunting the wind are the only ways around the nose... but you have to do them all!
