From campsites deep in the woods to crowded urban centers, stay comfy and look sharp with the help of the Mammut Men’s Alvra Long-Sleeve Shirt. Mammut crafted this versatile button-up with a soft, moisture-wicking fabric that features temperature-regulating merino wool to help you stay comfortable whether you’re warming up with a hike or cooling down with a drink. And with its understated check pattern, the Alvra looks just as at home in the mountains as it does at the mall.
