My body shape is frustrating to find things that fit me correctly. Wide shoulders, short torso, long arms. I bought a rain jacket several months back. The large was too baggy so I elected to go medium. Off the bike it fits fine, arms just a touch short, on the bike the arms go half way up my for arms, and the back of the jacket doesn’t cover my lower back. The good news, it doesn’t act as a parachute.
