The Glacier Collection celebrates first ascents of some of the most iconic summits in the Alps. And this season, we've worked with S.Café® that uses recycled coffee grounds to create a fabric that's not just eco-friendly, it's highly functional, too. This unique yarn actually helps to lower your body temperature by 1-2ºC, it's moisture wicking and dries quickly. We've also added small perforations under the arms and across the back to allow your skin to breathe. So the Glacier T-Shirt is the ultimate warm-weather hiking partner.
