This is a surf nylon hooded jacket produced in Hawaii in the 1980s.
I think it was a brand that hardly appeared on the market in mainland America or Japan at the time.
This is a local brand that is sold at some SURF SHOPs in Hawaii.
The nylon is relatively thick and sturdy, and the color is a beautiful green with a slight blue tinge.
It seems to go well with denim, etc., and can be enjoyed as casual wear.
