Really like these pants. The material seems tough and strong, ready to take on just about any thing I put them too. Lots of reinforced material in the foot cuffs.
The vents are on the outside of the thigh and run the length of my thigh, Mesh under the zipper. I would've like to have some crotch vents as well and don't care much for the mesh, I get hot easier and would like some extra airflow from time to time. I did buy these for the colder ski days, as i have a pair of non-insulated pants for warmer days, so the issues are pretty negligible.
Only 1 back pocket and 1 cargo pocket, would've prefered 2 of each, but there are enough as is, I just like lots of pockets.
Mine were larger than I expected. I am 6.2, 190 lbs. Waist 34. Went with a large, which is what the size chart said and the waist was very big. Inside the waistband, however, are adjustable velcro straps to tighten up the waist band. Along with a cool belt I am now good to go!
