You have to move in it.

Standing in front of a mirror is one thing. Turning through a shot, reaching into your bag and spending an afternoon outside asks a little more of a shirt. The same goes for what you wear when the morning is cool and the afternoon has other plans.

Find something you like the look of, then check the fit, fabric and details on its page. Sizes can vary between brands, which is why “I’m normally a medium” is the beginning of a conversation rather than the end of it. If you’re deciding between two, give the Pro Shop a call. Looking comfortable is much easier when you actually are.
