Pants overall construction is very good. i did end up returning them due to the knee pad flap protector is only held in place once up by two small pieces of Velcro. From experience I knew that wouldn't hold at all so rather than use them I returned them immediately. If you can get past that or just not use that aspect of the pants they're great. Fitment is spot on.

I wore these for duty for about 5 months and these are my thoughts.
TL;DR I liked them
If your using these for airsoft or anything low stress they will be fine, they fade over time but as I write this still black, although what gets bloused into my boots vs the rest are different shades. They do stain, though not with what you think, be it experience with washing blood and suspicious goo, or what have you they clean up well, with hand sanitizer being my only blobs.
NEEDS MORE BELT LOOPS!
Like I said wore them for duty holding my all leather belt, and all my gear. None of the belt loops failed but definitely need more to hold the base belt close so I can secure my duty belt. Specific at around 4 o'clock, and 7 o'clock.
Knee pads are Lifesavers, and pants are designed to show or cover them which is awesome as I have to keep them covered.
For guys familiar with the issues from army issue, I blew out the crotch within the last week or so, along with a year in the thigh where it's not reenforced.
All in all I like them, they aren't crye g3's but neither is the price.

So well made I bought a 2nd pair in multicam. I use these for hunting as well as general work around my ranch. These have more pockets, hidden pockets, and zipper vents than I can count. Extremely versatile and comfortable.

Great pants.
fits great and well made. wear them for training and on Duty.

Best all-purpose heavy duty work pants I've ever bought!! 6 months in after doing roofing , lawn Care , fall cleanups and snow removal and nothing wrong except for holes being rubbed into the inner thighs due to daily use!! suggesting secondary reinforcement layer for inner thighs!! Almost forgot to mention with the knee pads included they are definitely a lifesaver!! because I dislocated my left knee three times and has made it difficult to crawl or even just kneeling down on that knee therefore the knee pads are incredibly helpful and giving me confidence to do everyday tasks without having to worry about my knee because I can use the straps in the back as a compression system on my knee as well as keeping the knee pad in place!!!
