I have two new in the package without tags DCU USMC Gen 1 ECWS parka's. Both size XL short. They are the early version parka with PTFE liner. Just as water and wind proof as the Gen 2 parka's.
They have two very large deep front pockets, much softer and quieter than the Gen 2 parka's. They have hoods that don't roll into the collar. I also have the matching trousers in XL REG. NSN 8415-01470-2841S.
I'm not sure what company made this parka,it doesn't say on the tag.
