From Duck Head: " Introducing our most comfortable performance button-downs yet. This season we managed to make our performance fabric even softer. What separates our performance button-downs from the competition is the added Tencel fibers. Tencel offers a soft natural touch, breathability, and moisture wicking so you won't feel stuffy when layered under a pullover or sweater. You'll also save time thanks to its easy-care blend. Pull it out of the dryer and you're off to the office or your next outdoor adventure."
Sizing: Runs True to Size. If wider in the shoulders, we recommend sizing up.
