The Hiking Patrol x Mammut Light FL Half Zip T-Shirt is a high-performance first layer designed for multi-sport use across demanding mountain terrain. Its body-mapped mesh construction delivers targeted ventilation and a barely-there feel, while natural sweat-wicking properties support effective temperature regulation during high-output efforts. The half-zip collar adds versatile airflow control, and quick-drying, odor-inhibiting performance keeps the shirt functional across extended wear. Sizing runs large — selecting one size smaller than usual is recommended.
