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 fabric dries four times faster than cotton while feeling just as soft, and to prevent rubbing from backpack straps, the shoulder seams are shifted back. The design features the 4,208-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, pleasant fabric made from recycled polyester and organic cotton, Drirelease® technology: improved moisture transport, faster drying, and more comfort with natural and synthetic fibers, easy-care, wrinkle-resistant, and no ironing needed.
