I have to go out of my way to find clothing that isn't scent lock type. I don't buy the hype for any of that stuff. Even if it works, it is going to wear out pretty quick after a few washings. Plus it does nothing for scents on the outside of your clothes. How many times do you see them on the hunting shows wearing scentlok and then still trying to stay downwind of the deer? You also see them getting busted when a deer gets downwind from them and they use every scent product on the market.
I buy regular hunting clothing and use unscented deo and scent free wash. That is about the best you can do IMHO.
