Button up, cool down, and breathe easy every step of the way. This collared staple keeps you comfortable in changing conditions thanks to quick-drying AirExchange perforated fabric and roll-up sleeves you can adjust as the day unfolds. Micro holes throughout the shirt allow air to flow while wicking sweat away, so you stay cool no matter how long you stay out. Flat-felled seams boost durability and comfort under the weight of your pack, while a single drop-in chest pocket lets you stash sunscreen, sunnies, and lip balm for long days outside. The straight hem is ideal for wearing untucked, whether you’re scrambling up rocks or loading up your pack, while the breezy button-up design provides ventilation that helps you go with the flow for virtually every activity under the summer sun.
