Natural moisture management Inspired by and named after Monte Zebrù in the Ortles Alps and made in Italy, our Zebru Fresh bodymapping baselayers are made primarily of superfine merino wool blended with durable Tencel™ Lyocell from sustainably grown wood. The merino wool provides optimal warmth and next-to-skin comfort, while Lyocell ensures additional moisture absorption and freshness. Improved thermoregulation Added to the natural fibers are smart synthetic yarns enriched with a unique blend of natural thermoreactive minerals. These Responsive yarns are able to absorb Far Infrared Energy (FIR) from your body and slowly release it back into your muscle tissue over time. The resulting increased blood flow, cellular performance and oxygenation leads to more effective thermoregulation, improved performance and faster recovery. Responsive is an integral part of the fabric and does not wash out. The long-sleeve men's version of this baselayer has a body-hugging, athletic cut and requires no elastane for stretch. The 28% polyamide content also makes it more durable and dimensionally stable. An advanced circular knitting process creates a seamless, one-piece top for increased comfort without chafing. And thanks to the 36% merino wool content, the Zebru also naturally inhibits odor. A lightweight, moisture-regulating merino baselayer for intensive use in changeable mountain weather. Responsive technology: thermal regulation & recovery. High merino wool content: breathable, heat insulating, for a natural feel against the skin. The combination of merino wool fibers and Tencel® cellulose fibers of plant origin increases the absorption of moisture released by the body and provides a cool and dry feeling Jacquard pattern Flat seams on the sides Comfortable fit due to flat seams
