The Circadian Collection is built for moving fast and light along the trail, but always protected. And with this t-shirt that means protected from sweat build up and the cooling effects of damp clothing. Thanks to FlashDry™ technology and mesh under the arms and over the upper back, your skin can breathe, sweat is wicked away and the t-shirt dries in a flash. All this helps to regulate your temperature and allows your body to perform at its best when hitting the trail.

    Reflective elements ensure the wearer is seen and safe in low-light conditions.
