It's only as important as the guy trying to sell you the product....I have been within 20 yrds or closer to alot of critters... The only scent control I use is scent free soap and shampoo...I also cut pine branches off trees and put them with my camo's in an airtight bag.. Other than that I go through the woods as quiet as a cat.. I have an idea...try chewing on some deer dung...You well smell just like them..good luck to all..
