Whether for all-day hikes, climbing walls, or everyday wear, this T-shirt keeps you cool and dry even in humid, hot conditions thanks to Drirelease® technology. The moisture-wicking material dries four times faster than cotton while feeling just as soft, and to prevent chafing from backpack straps, the shoulder seams are set back. The design features the 3308-metre high Piz Badile and pays tribute to the mountaineering legend Stephan Siegrist, who has been a Mammut athlete for 30 years. You'll see: this versatile mountain T-shirt is always reliable.
