The US one is the pattern for all others. Back in the early 90s when they - our superiors - told us we were getting the Ranger blanket we were all elated. Our hopes were dashed when they were OD in color, and were not very compact.
THEN we found out that because the CAF had a shitload of old green rain jacket material left over and TB was not going to let that go to waste, that's what ours were made of. They were like a moving blanket.
A few years later the current light weight ones (at least in my day) came out . We exchanged them one for one.
