I hunt alot more with my Cabela's Gore-Tex Gaitors than any of the others that I have. Not only do they keep the snow or water out of the tops of the boots, but they also keep the lower legs warm(er) when really cold.
I don't use the shorter ones. I much prefer the tall models and run them with the tops open to allow moisture to escape. If I need to close the tops temporarily, that's easy to do.
I might add that I use them with wool pants which help with the moisture accumulation problem. If i'm using some sort of wind proof pantts like my Patagonia Ether Pants, then I Venti-Gaitors. E
