I bought my ECWCS gen II parka off base in Florida in the early 1990s. It’s got goretex, a cobra hood, two way zippers that you can unzip from the bottom if you want to, underarm zippers for cooling, and will keep you warm in the snow.

I love mine very much. Big pockets too. You can get them on eBay. At one point amazon had them, IDK if they still do. Mine is woodland camo because it was actually part of a uniform, but at one point they were also available in black and also ODG.
