This is the summer's answer to your favorite chore jacket. Form & Thread's brand ethos is “to do simple things exceptionally well.” And they accomplish that with every single garment they produce. This is made from shirting material, so it's extra light and breathable, but gives you the layering ability (and pockets) of a jacket that you can wear despite summer's inhospitable heat and humidity.
