The Salewa Zebru Responsive Longsleeve Tee Men in the Onyx colour is a men's thermal base layer designed for high-intensity alpine activities, including trekking, mountain running, and ski touring. Its advanced Responsive fabric technology provides excellent moisture management, thermal regulation, and next-to-skin comfort throughout demanding mountain adventures.

• Responsive Technology: the advanced fabric efficiently manages moisture and responds to body heat, helping keep you dry and comfortable during intense physical activity.
• Thermal Regulation: the balanced warmth-to-weight ratio provides reliable insulation in cool mountain conditions while preventing overheating during high-output efforts.
• Ergonomic Athletic Fit: the close-fitting stretch construction follows natural body movement, delivering unrestricted mobility on demanding terrain.
• Odour-Resistant Finish: the integrated anti-odour treatment helps maintain long-lasting freshness during multi-day adventures and extended mountain activities.
• Flatlock Seams: strategically positioned flat seams minimise friction and help prevent chafing beneath a backpack or climbing harness.
• Ideal for Layering: the slim-fitting design sits comfortably beneath a mid layer or waterproof shell, making it easy to adapt to changing mountain conditions.
