I am 5’6”, ~130lbs and I bought this in a medium, purposely sized up to make it a super casual, beach/lounge vibe shirt and it’s perfect. It’s seriously so comfortable, the hood is perfect to hide away from the world and it’s the perfect in between temperature, not too hot or cold, so perfect for light fall or spring days. Of all the designs I wear by this company, the Buddha feels protective and wise.
