The Black Diamond Men's LS Stretch Technician Shirt is a button up shirt that won't say no to a bit of travel, climbing, bouldering, hopping into the woods, and a drink or two at the local watering hole. The cotton, polyester, elastane blend is soft against the skin and has just enough stretch to move and follow the body, especially when reaching for the next hand hold. Collared for looking good around town, plus two chest pockets for holding onto notepad and pen. Or smartphone. Unplug, plugged, it's up to you.
