Does anybody have any experience with this line?

Ticks are just terrible in the Bitterroot and Selway in the spring, and I want to get some bear hunting and elk shed hunting done without risking the fever.

I have tried bathing in deet and treating all of my clothes with permethrin, but I am still always picking the devils off or feeling them crawl into my hair. This stuff looks like it could be the firm barrier I am looking for.
