A running shirt that doesn't look like a running shirt.

The S-Ridges is Fractel's Coolbreeze adventure shirt in blue, an open-knit mesh designed for exceptional sweat-wicking breathability. The button-up front opens on the fly for ventilation when the heat kicks in, and the relaxed, structured silhouette moves with you from the trail through whatever comes after it. "May be the most unique running shirt I've come across," Matt Rasmussen wrote for Run Oregon.

• Coolbreeze recycled open-knit mesh: sweat-wicking breathability with an airy, four-way stretch feel
• Button-up front that opens for ventilation: a relaxed, structured silhouette that moves with you
• Reads smart-casual off the trail, not just technical on it
