I use the KUIU Kutana gaiters, from the first time I bought them I never go without unless it's exceptionally hot. I like them for several reasons, when it's cold, they prevent cool air from working it's way up your pantleg. They keep the uppers of your boots and pantlegs dry and they keep all sort of debris from getting in your boots. If you step in water over your boots, it keeps them from flooding momentarily. I have a camo pair for hunting and a solid pair for hiking. The greatest innovation for hunting, at least for me, in years!
