Mammut's attention to detail shines through in every piece, with ergonomic designs that move with your body and flat seams to prevent chafing. Whether you're scaling peaks, carving down slopes, or embarking on a multi-day trek, our base layers keep you dry, comfortable, and focused on the adventure ahead.
