A men’s technical merino baselayer that offers lightweight warmth and thermoregulation to keep you warm, dry and comfortable during alpine mountaineering, ski mountaineering speed hiking and alpine trekking.
Enhanced heat regulation
Named after Monte Zebrù in the Ortler Alps and made in Italy, the Zebru is composed primarily of super-fine merino wool for optimal wicking warmth and next-to-skin comfort. Designed to push moisture away from the skin, it dries quick and provides scientifically proven enhanced thermoregulation. As such, it’s the ideal choice for high-intensity alpine activities in cold-weather scenarios.
FIR textile technology
Built with a body-mapped design to help you enjoy your activity more and for longer, we combine merino and polyamide fibres with Responsive smart synthetic yarns that contain a unique blend of natural Thermo-reactive minerals. Responsive has the ability to absorb Far-infrared radiation (FIR) from your body and slowly release it back into the muscle tissue over time. The resulting increased blood flow, cellular performance and oxygenation leads to longer-lasting warmth, better performance and faster recovery. What’s more, Responsive is permanent and does not wash out.
The Zebru Long Sleeve has a tight, close-fitting athletic cut that requires no elastane, while its polyamide content makes it more hardwearing and supports shape retention. The advanced circular knitting process results in a seamless one-piece torso for greater comfort without chafing. Thanks to its high percentage of merino wool (64% WO 36% PA), the Zebru also naturally fights body odour build-up. A technical long-sleeved merino baselayer that offers wicking, warmth and temperature regulation for high-intensity use in varied conditions.
