“I’m a 39-40 chest, 31” waist. While I normally grab M, I bought the small; it’s a trim fit, clean look and wicks like you have a a built in dehydration unit to your shirt. Texas has been hot this summer, like 100+ hot in late afternoons, so I soaked the shirt in cold water, wringered out and wore it wet for a 30min recovery run. Great run! It’s a great sink wash, wringer, and hang dry and damp wear to grab a bite to eat. It drys wrinkle free.”
