These pants have been the best waterfowling pants I have owned so far. This season I have used the Sitka Grinder pants in all conditions from hot, sunny September Goose season all the way to the other end of the spectrum on cold, windy January duck hunts. The Grinders handle it all with ease. They are great to wear alone, or with underlayers for field hunts but they also do great when worn under waders for water-based hunting. I am a gear tester for Gore-Tex so you know I am a gear nerd, but these pants have met my expectations for quality and design. Highly recommended.
