scentlok or scentblocker is juat another great advancement for the sport and it has been proven time and again by prostaffers and every day hunters that it does work. just as camo advanced and every other product that comes out to do the same thing. and that is to tip the odds for success in the hunters favor. maybe it is over priced but noone said the sport of hunting is cheap. like anything else you get what you put into it.
