My quick observations,
1. On the Crye Combat Pants, the immediete area around the knee pads is constructed with a multicam fabric.
The Gen 1 Combat Pants had 500d Multicam Cordura around the knee pads
The Gen 2 Combat Pants has the same fabric as the pants around the knee pads.
If you look at the this pic http://i296.photobucket.com/albums/mm19 ... c/sasE.jpg
you can see that the area around the knee pads is khaki/Coyote Tan (note I'm not talking about the stretch panel but literally the material on the immediete outside of the knee pad).
2. The Knee Pads have the sideways "engraving" for lack of a better word on them, which are very similar to (if they aren't) the "OPS" branded knee pads seen here http://www.ur-tactical.com/index.php?pa ... t&Itemid=3
When I first saw the knee pads I assumed they were the OPS pants, I checked out the offerings from "OPS" which are
"OPS Ultimate Direct Action Pants"http://www.ur-tactical.com/index.php?pa ... t&Itemid=3
"OPS Integrated Battle Pants"http://www.ur-tactical.com/index.php?pa ... t&Itemid=3
but if you look closely and compare, they are different, like the Crye Combat Pants, the OPS Pants also have a Multicam fabric around the knee pads.
There are a few other companies now who are making there own uniforms which are similar to the Crye Uniform's so it could be any of them but I'm not too familiar with them.
Anyway, just my quick observations and more than happy to be proved wrong, only really started looking at the Crye stuff in the last 6 months or so
Thanks for posting the pictures by the way.
