A high-performance thermoreactive men's tight made with merino wool and stretch content, the ideal baselayer for alpine mountaineering, ski mountaineering, speed hiking, or alpine trekking. Optimal thermal regulation helps you maintain your body temperature and ensures you don't cool down in colder weather. The Zebru Responsive Tight provides the warmth and freedom of movement you need. It's breathable, dries quickly, and takes up little space - the perfect solution for your layering system.

The main component of the material is superfine merino wool (83%), which offers optimal thermal performance and moisture management, improving temperature regulation. This blend of merino wool and polyfibres is combined with special responsive polyamide yarns, forming a matrix for a unique blend of natural thermoreactive minerals. Responsive absorbs the body's far infrared radiation and gradually releases it back into the muscle tissue. In tests, subjects wearing Responsive were found to have greater blood flow, higher cellular performance, and better oxygenation. This means you perform better, recover faster, and stay warm longer.

The tight features body mapping construction made using an innovative circular knitting process that uses very few seams, ensuring it sits comfortably against the skin without rubbing. It has a close-fitting, sporty cut, is super soft, and thanks to the elastic yarns wrapped with nylon, it also has four-way stretch. Merino wool is naturally odour-resistant, allowing your tight to stay fresh longer. You can wear them longer and wash them less often, saving time, water, and energy. This lightweight tight with body mapping construction is inspired by Monte Zebrù, a mountain in the Ortles Alps. Made in Italy, it offers stretch comfort and improves thermal regulation.
