Salewa Zebru Responsive T-Shirt Functional Shirt

Our warmth-regulating, breathable men's baselayer features merino wool and infrared fabric technology, ideal for alpine mountaineering, ski mountaineering, speed hiking, or alpine trekking.

Better thermal regulation: The Zebru baselayer provides just the right amount of warmth during intense activity in cold weather, helping you regulate your body temperature. This 83% merino wool T-shirt wicks moisture, dries quickly, and enhances thermal regulation.

Advanced infrared material technology: Inspired by Monte Zebrù in the Ortler Alps, this T-shirt is made in Italy with fine merino wool, offering optimal thermal performance and moisture wicking while feeling comfortable against the skin. The merino wool-polyfibre blend is complemented by special Responsive polyamide yarns, which contain a unique mix of natural thermoreactive minerals. Responsive absorbs the body's far infrared radiation (FIR) and gradually releases it back into the muscle tissue, similar to how a south-facing rock face stores and releases solar energy. This improved thermal regulation enhances well-being and blood circulation during activity, while cellular performance and oxygenation are also boosted, helping you stay warmer for longer. Responsive technology is a permanent fabric component and will not wash out.

The Zebru is soft against the skin, features a sporty cut, and incorporates a body mapping design. The polyamide yarns enhance the durability of the T-shirt, ensuring it retains its close-fitting shape. The upper body is constructed from one piece using an advanced circular knitting process for greater comfort without rubbing seams. Additionally, merino wool is naturally odour-resistant. This heat-regulating technical T-shirt with merino wool is perfect for intensive activities in the high mountains.
