KalzasM. 1/2 is a performance-oriented short-sleeved men's jersey – built for demanding rides. Crafted from MoonDry, a lightweight, breathable fabric made of 100% recycled polyester, it ensures fast moisture transport and a comfortable feel even under strain. The jersey features elongated sleeves, a low round collar with small insert, a full-length front zipper, and three rear pockets, combining comfort, performance, and a sleek, sporty design. The reflective details enhance visibility in low-light conditions. Thanks to Polygiene® StayFresh™ technology, odor-causing bacteria are neutralized, keeping the jersey fresher for longer and reducing the need for frequent washing. The Rainbow Mountains transfer logo on the chest and back adds a stylish Maloja signature.
