I ordered a Medium in this so I could wear a sweater under it, but I could have ordered a small. I'm 5 ft. 4 in. 119 pounds. The Medium looks good although the sleeves are way too long, but not a problem because I rolled them up. However, I walked on a cool day with a short sleeve T-shirt underneath, and the jacket held sweat as if I'd dipped it in a swimming pool. I couldn't believe how wet it was. Two hours later, I picked it up to wear outside again, and the jacket was still wet!Several months later, I've upgraded my view of this jacket. I've worn it on a couple of trips now, and it looks great, is so practical, folds up in my backpack, has usable pockets, and is a great little windbreaker. One problem, though. I left it in the motel room on my last overseas trip, so I might order another one.
