We have just returned from safari and are going over what worked and what didn't. One thing that worked, but not as well as we would have liked were our Carhartt Washed Duck Work Dungaree 12 oz cotton canvas. Seems that more than one time we each ended up with Prickly Pear thorns in our legs. To that end I'm researching Upland Game/Briar Pants for our next trip. So far I've come up with a few choices (in no particular order) Filson Dry Tin Cloth 5-Pocket Pants Filson Double Hunting Pants Orvis Missouri Breaks Briar Pants Gamehide Briar Proof Pants Wondering if anyone else is using or considering such options and would like your views.
