I think scent lok may be good for hunters that aren't as skilled at Scenting down as well as the veteran hunter.
Some hunters use scent sprays and think they've done enough, it isn't. Like Huntingman says scent eliminator sprays, soaps, shampoo's, launry detergents, deodorants, those are all important steps needed to reduce odors and scents,
the scent lok clothing may add an edge, (maybe not) I don't know but I do know it's very costly and may not be worth it.
Hunters have been successfully harvesting wildlife for hundreds and hundreds of years without scent lok BUT if the scent lok manufacturers want to send me samples, they can email me for my mailing address and I'll gladly give their product a try...
