Salewa Shirt Zebru Fresh AMR is the perfect shirt for alpine mountaineering. Natural moisture management Inspired by and named after Monte Zebru in the Ortler Alps and made in Italy, our Zebru Fresh bodymapped baselayers are composed primarily of super-fine merino wool blended with high-tenacity Tencel™ lyocell extracted from sustainably grown wood. The merino provides optimal wicking warmth and next-to-skin comfort, while lyocell brings additional moisture absorption and freshness. Enhanced thermoregulation Added to the natural fibres are smart synthetic filaments loaded with a unique blend of natural thermoreactive minerals. These Responsive yarns have 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 more effective thermoregulation, better performance and faster recovery. As such, Responsive is an integral part of the fabric and does not wash out. The long-sleeved men’s version of this baselayer has a tight, close-fitting athletic cut and requires no elastane for stretch. The 28% polyamide content also makes it more hardwearing and shape retentive. Made using an advanced circular knitting process, resulting in a seamless one-piece torso for greater comfort without chafing. And thanks to its 36% merino wool content, the Zebru also offers natural odour prevention. A lightweight, wicking merino baselayer for high-intensity use in changeable alpine conditions.
