Nike size small, thin fluorescent, green waterproof jacket

This is very thin material and it doesn’t have a size mentioned, which is why I’ve included the measurements. I would say it is a size small which best fits a women’s 4 as I am a6 and it was a little bit too tight It’s a very basic jacket I’m not sure if it’s 100% waterproof although it seems to be however the tags have minimum information on so I can’t say for sure
