The Amberjack shirt from Poncho is made from proprietary fabric that is breathable, lightweight, quick-drying, and provides built-in sun-protection so you can stay out all day. It’s got built-in stretch to keep you moving, and tons of thoughtful details born from our time spent outdoors — like a hidden zippered pocket, sunglasses holder, and more. It’s the shirt we wanted to wear, so it’s loaded with everything you need, and nothing you don’t.
