Definitely a unique trouser design that'll stand out from the crye copies (if that's your goal).  Made from legit 50/50 NYCO Pencott fabric, well stitched, also rather expensive at retail and not available in the UK that I've seen:

I've actually written a piece going over ALL the details and features which you can read here for details:

Sizing is 'Medium' so if you're in or about that 32" waist range and average height you'll be good to go.  They seem to line up with all the other Medium or 32R size trousers I've got from many other brands/issue kit.

The D3O knee pads are NOT included in this sale, however if you don't want to shell out on those then literally any bits of foam can be stuffed inside the knee pad pockets.

Price is all-in with postage included.  Everything else I have for sale is also pictured here - https://flic.kr/s/aHsjPXJkHw
