Also using these this year for the first time and happy with them.I'm 6'5" 250, 36x36 normally. This is what I've worn this year and they have held up great, I've put a lot of miles into them through brush and they have no rips and are actually quite comfortable, lightweight, waterproof, warm enough.

I bought a pair with suspenders this year and i love them, so far they have held up nicely.
Had a pair of these (Carhartt Double Front) myself. Good quality and serviceable if you overlook the built in brush hook (I think they consider it a hammer loop, but I never carry a hammer when bird hunting. Only real downside was - these are heavy when wet.Carhartt Firm Duck Double Front Work Dungaree Pant B01 been using these all season 50 bucks in your size I would not hesitate to order another pair.
