Most comfortable rain jacket I have ever tried on! The lining feels really nice and soft and the vinyl is so fluid and flexible that is moves easily with you. Similar one online was dated from the 80s but I am thinking it could maybe be from the 90s instead. Brand is Karen Kane Easywear. Size Large. Material is 62% Vinyl, 28% Polyester, and 10% Polyurethane. Lining is 100% Acetate.

-Across chest 26"
-Length from top of shoulder 32"
-Sleeve length underarm to underarm 18"
