I have both FROG and MCCUU.

The FROG pants are a slightly different cut than the usual utility trousers (most immediately noticeable are the pockets on the calves), and obviously they're made of flame retardant material instead of ny/co; otherwise the material for the Woodland FROG trousers seems of similar thickness/strength as regular MCCUU trousers while the Desert FROG trousers are made of a lighter material. While the material is thinner/lighter/cooler, its still resistant to normal wear however I'd presume it would be more easily damaged if snagged on a sharp broken branch or something.

The FROG trousers, especially the WL ones, also seem to fade faster in the wash. Nothing drastic but I did notice a difference after the first wash -- and I'm meticulously careful about this stuff, my MCCUUs still look pretty new.

The FROG shirts, on the other hand, are entirely different than the MCCUU blouses: the material on the arms (camo) is fairly thick and resistant but the torso is made of extremely lightweight, breathable whicking fabric (Tencate Defender M), which while resistant to normal wear and tear (again, keep in mind the stuff is designed for military use, not cocktail parties) it probably is more easily ripped/damaged than the MCCUU blouse. That being said, it's supposed to be worn under body armor so its not going to be that exposed to damage anyway.

So bottom line: Desert FROG is great and lighter in warm weather, Woodland FROG you m̶i̶g̶h̶t̶ probably want the shirt but you can pass on the trousers unless you're looking to put together an accurate impression.
