In the mountains, good equipment is half the battle - and this starts directly on your skin. Because there is nothing more unpleasant than the irritation of damp undergarments clinging to your skin when climbing, hiking or on a ski tour. Luckily, our Eiger Extreme Collection includes the Moench Advanced ML Half Zip Longsleeve Men. The combination of very lightweight Polartec® Power Dry® and highly elastic Polartec® Power Stretch materials keeps you cozy and warm and fits like a second skin. The collar is cut high and the chin protector does not chafe. And, to allow you to slip your favorite longsleeve on again the next day, the Moench Advanced ML Half Zip Longsleeve Men has an antimicrobial treatment. Which means: it stays fresh for longer than your leg muscles.
