It doesn‘t surprise me to see that uniform on ebay. I was re-issued kit this year from stores in St. Jean because I had to hand in my kit from the reserves, quit the reserves, in order to re-enroll under ROTP. When I handed in my uniform, it was what we see in the first link posted on page one of this thread.
The uniform I have now, is different in the respect that the buttons that you see, are covered on the new versions of the uniform. Some bright person somewhere realized that the buttons heat up in the sunlight, and can be easily spotted using IR technology, thus defeating the purpose of all the expensive fabric treatments. So the new versions have covers for the buttons on the front and the pockets. My theory is that they are phasing the old CADPAT out as surplus.
As for mixing it up with the Marine uniforms, who cares...they‘re not ours, and the colours are distinctly different (uglier I might say, but whatever)
