These pants are sick. I got them in XXL. I'm 6'8 195 pounds so the 35 inch inseam on the XXLs was a must. They are huge on me but not poofy big. the waist gaiter fits nice and im a 36" waist. theres too many pockets to count and the 4 vents will really dump excess heat. also the pullstrings inside 2 of the pockets are funkin awsome. no more shredding the cuffs of my pants. cannot comment on the water proofing as i have yet to field test these things but im pretty confident the 15k will hold up stellar son.
