Salewa Zebru Responsive T-Shirt Functional Shirt

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

Better thermal regulation is achieved with the Zebru baselayer, providing just the right amount of warmth during intense activity in cold weather conditions while helping to regulate body temperature. This 83% merino wool T-shirt wicks moisture, dries quickly, and enhances thermal regulation.

The advanced infrared material technology is inspired by Monte Zebrù in the Ortler Alps (3735 m). Made in Italy, the primary ingredient is fine merino wool, which offers optimal thermal performance, moisture wicking, and comfort against the skin. The merino wool-polyfibre blend is complemented with special Responsive polyamide yarns that contain a unique mix of natural thermoreactive minerals. Responsive yarns absorb the body's Far Infrared Radiation (FIR) and gradually release 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 also improving cellular performance and oxygenation, allowing you to stay warmer for longer.

Responsive technology is a permanent fabric component and will not wash out. The Zebru T-shirt is soft against the skin, features a sporty cut, and a body mapping design. The polyamide yarns enhance the durability and longevity of the T-shirt, ensuring it retains its close-fitting shape. The upper body is crafted from one piece using an advanced circular knitting process, providing greater comfort without rubbing seams. Additionally, merino wool is naturally odour-resistant. This heat-regulating technical T-shirt is perfect for intensive activities in the high mountains.
