Brandon: For what it is worth, I have hunted birds in Eastern New York and Southern Vermont for 35 years now with my dogs. In years past 20-30 days a year. I experimented with many pants, including the Filson Tin Cloth field pant. They were like wearing armor and I wore my set out in one season. (I may have gotten a "lemon pair). I have not tried some of new ultra expensive pants from Orvis, et al. But I will tell you that a guy I used to hunt with who hunted with his dogs every day 50 odd days a year---used only Carharts. My favorite pair were an old set of Duxbacks, canvas and reinforced knees--needless to say no longer made. Few pants are briar proof but they were as good as the Filsons--and comfortable. I have since tried to find a similar pair and am now using the Bean's Katadin Iron Works pants. There are relatively inexpensive and I have had my set for a couple of years--though admittedly I am not hunting birds 20-30 days a year.
