I hunted for 5 solid days in the rain in Texas this year. I think Tx gets about 10 rainny days annually and 5 of them happened to be the week I was down there hog hunting.

In any case. I had the Cabelas Dry Plus, and was very pleased with the performance. I was able to stay out all day and stayed plenty dry. While GoreTex is nice stuff it is quite costly. The Dry Plus is a good alternative.
