A high-performance thermoreactive men's tight made with merino wool and stretch content, ideal as a baselayer for alpine mountaineering, ski mountaineering, speed hiking, or alpine trekking. It provides optimal thermal regulation, helping you maintain body temperature and preventing cooling in colder weather. The Zebru Responsive Tight offers warmth and freedom of movement. It is breathable, dries quickly, and takes up little space, making it the perfect addition to your layering system.

The main component of the material is superfine merino wool (83%), which ensures optimal thermal performance and moisture management while enhancing temperature regulation. This tight combines a mottled blend of merino wool and polyfibres with special responsive polyamide yarns, creating a matrix that incorporates natural thermoreactive minerals. Responsive technology absorbs the body's far infrared radiation (FIR) and gradually releases it back into the muscle tissue. Tests have shown that subjects wearing Responsive experienced greater blood flow, higher cellular performance, and better oxygenation, resulting in improved performance, faster recovery, and prolonged warmth.

The tight features body mapping construction, utilizing an innovative circular knitting process with minimal seams for a comfortable fit against the skin. It has a close-fitting, sporty cut, is super soft, and incorporates elastic yarns wrapped with nylon (Corespun process) for four-way stretch. Additionally, merino wool is naturally odour-resistant, allowing you to wear the tight longer and wash it less frequently, saving time, water, and energy. This lightweight tight, inspired by Monte Zebrù in the Ortles Alps, is made in Italy and offers stretch comfort while enhancing thermal regulation.
