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 but feels just as soft. To prevent chafing from backpack straps, the shoulder seams are shifted back. The design features the 4208-meter high Grandes Jorasses and pays tribute to the climbing legend Stephan Siegrist, who has been a Mammut athlete for 30 years. You'll see: this versatile mountain T-shirt is always reliable. Enhanced comfort with shifted shoulder seams to avoid pressure points under the backpack. Comfortable fabric made from recycled polyester and organic cotton, Drirelease® technology: improved moisture transport, faster drying, and more comfort with natural and synthetic fibers. Easy to care for, wrinkle-resistant, and no ironing needed.
