Stay comfortable on your summer trips with the Jack Wolfskin Rays Stretch Vent from Eastern Mountain Sports – the shirt that does it all. The light nylon fabric is super stretchy, so it adapts to every move you make. It also offers great UV protection and dries fast, even when it's soaked in sweat. The stay-fresh properties are a real advantage on multi-day trips. And, the ventilation slits are a welcome addition, particularly in warmer weather.
