One of the best things I've ever purchased
Incredibly comfortable, works with any outfit. Just an incredible piece that I hope to wear forever. Consistent wear for a month in NYC and it's held up very well so far. For sizing, I'm 6'1 175ish and got a large. The medium could've worked but was a bit more snug around the under arms and shorter on the arms. I like wearing layers under, so went with the large.
