I've been wearing a set of Gamehide Elimitick pants and button up shirt for about five years. I used to get a tick or two attached every time I hunted in W. Ky no matter how much spraying I did. Since I have been wearing the Elimitick, I have never found a tick attached. I spray my snake boots, hat, vest, etc and tuck the pants into my snake boots. They absolutely work. Size ran true for me.
Now, for the bad. The fabric is a very tight weave and they are very hot. They do not breathe nearly as well as cotton or a cotton/poly blend. That's fine in cool weather, but I sweat a lot when wearing them in hot weather. Worth it though IMO.
