Whether for all-day hikes, climbing walls, or everyday wear, this T-shirt keeps you cool and dry even in humid and hot conditions, thanks to Drirelease® technology. The moisture-wicking material dries four times faster than cotton while feeling just as soft. To prevent rubbing 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 find that this versatile mountain T-shirt is always reliable. Enhanced comfort is provided by the shifted shoulder seams to avoid pressure points under the backpack. Made from a pleasant fabric of recycled polyester and organic cotton, Drirelease® technology offers improved moisture transport, faster drying, and more comfort with natural and synthetic fibers. Easy to care for, wrinkle-resistant, and iron-free.
