I've been using it for 8 or 10 years now and love it. I think the best thing they have is the 3D suit; I wear whatever I want underneath. I can wear it pretty much anywhere and any season, and the critters can never quite figure out what you are, even up close. I've got several sets of the cotton tops and pants, but they aren't any good in the wet weather.
p.s., That's a sponsored opinion, but I wouldn't be using it if I wasn't positive it was the best.
