I'm 5'8" tall and fat (~255 lbs) I got size D112. I wear them with Craftsman Vest w/ Holster Pockets, The Redbacks Knee Pads, 8" work boots, a 2" wide belt and a tee shirt. I'm working refrigeration in a seafood plant in AK.
Mostly they work well. I like the total qty of pockets, and I like the polyamide in the pockets & knees. The innermost pair of front pockets are easy to access while working. I like the extra pocket behind the flap on the LH cargo pckt. The zipper length is good, & the belt loop placement also. I like the knee pads a lot.
These features benefit me. I don't use back pockets. I use hammer loops or any exterior loops without a pocket beneath them, as I don't want anything to swing freely where it might encounter the machinery around which I work. I like the idea of the non wicking cuffs, but I tuck them into my boot tops.
Things I'd change. Too long from the waist to the crotch. This makes the knee pads ride low. The knife holders at the waist, & outside the cargo pocket not long enough for my (one 18650 battery) flashlight. Maybe longer pocket w/ snap for a shorter knife - or two pockets, one for each. The individual tool pockets in front on the right side are small for VDE pliers - they work but not easily. I want a cargo pocket on the RH side like the one on LH - also a long pocket on LH, like on the RH. Probably the long pockets would have to overlap the outside of the cargo pockets some. That's fine. I wish all the individual tool pockets in front weren't only on the RH side, esp as the vest doubles down on that setup. I wish there were a couple little pockets for folded hex key sets. I wish there was a convenient pocket for one of the Wera screwdriver blades pouches - mine jams a little in cargo pocket.
Here's a comparison to another product - the ArborWear Tech II pants in 40x34, w/ legs hemmed to 30. They fit my body better at the top end, and I really like the pleat in the crotch for when I have to climb around on stuff. I also like the soft but durable microfiber fabric. It feels warm for the thickness in winter, while breathing well enough to be cool in the summer. OTOH, the microfiber easily gets holes from welding sparks. I like the inner flashlight pockets they put inside the cargo pockets. On the other hand, the JobMan front pockets are much easier to use, and the Arborwear pants don't have a lot of extra pockets, although they do have cargo pockets on both sides.
