Patagonia Men's A/C Buttondown Shirt

Lightweight, relaxed-wearing 100% organic cotton shirt with an airy, open weave for hot and humid climates.


  • Made of a crepelike 100% organic cotton crinkle fabric that lifts the A/C Shirt away from skin for a cooling airflow
  • Clean, button-front styling; left-chest button-through patch pocket and side vents for a greater range of motion
  • Straight hem goes with most every situation, from casual hangout to the workplace


  • Weight: 162 g (5.7 oz)
  • Material: 3.3-oz 100% organic cotton yarn-dyed plain weave (100% of the virgin cotton in Patagonia clothes is grown organically. Less than 1% of the cotton grown worldwide is organic)
