Outside of that:
The zipper pulls are a heavy metal but the teeth seem plastic; though they are still on the heavy side.
The sizes are S, M, L, XL (etc) and mine says L Intermediate (aka Regular) follow the sizing chart on that website. and possibly go one size up for added comfort (the suits in the movie were baggy anyway, it is just general practice). There is no storm flap.
I would suggest emailing them if you are really concerned about the zippers. They may be all metal by this point as the site says.
