When i first bought my scent lok clothes i was not sure if it worked, so i waited for really good sales and got scent lok clothes that i would ware wether or not its scent lok, so even if it dont work i still use it for the right weather conditions. For example i got Cabela's MT050® GORE-TEX® Scent-Lok®/pants for 100 bucks including tax!(normally costs 220) I would of bought them for that price even without the scent lok...
