I tried a set of MCCU's once, when the Marines were up at Wainwright for joint training. It felt like wearing garbage bags, in my opinion.
For most of my career we wore simple OD combat uniforms - for comfort and durability they were unrivalled but the top brass could never get around the Korea 'camo doesn't work' mentality. We use CADPAT now; similar material and make with excellent camo qualities. Here's a pic:

(Note: the bright Canadian Flag is only worn for garrison duty and exercises. During a deployment, the flag is replaced with a subdued light/dark green flag.)
The newer ones (pre-treated with insecticide) feel like heavy construction paper soaked in starch, which brings me back to the good old days of starching our cammies and polishing our boots everynight.
The green cammies are soft and comfy, like wearing a pair of PJ's with boots, but since deserts are the current battle uniform for USMC they are coming presoaked in bug spray and stiff as a board lol. Can't wait for winter when we switch to the greens again back here in the rear.
