Salewa Woman's Pants 3/4 Cristallo Warm Alpine Merino is the perfect base layer tights for high-intensity mountaineering in colder conditions. Our Cristallo 3/4 Women's Tights are designed to offer a warm texture and next-to-skin comfort for faster-paced mountain activities. Wicking, thermoregulating comfort Our hybrid merino wool and polyamide Alpine Merino Responsive baselayer fabric combines thermal efficiency with excellent moisture management. We enhance the synthetic core of its spun fibres with our proprietary Responsive technology – a special mix of natural thermoreactive minerals that recycles natural far-infrared (FIR) energy to improve your thermoregulation for greater comfort during activity. Responsive is an integral part of the fabric yarn and does not wash out or break down. Freedom of movement The polyamide content works together with the elasticated waist and gusseted crotch to ensure a trim, next-to-body fit and full freedom of movement, and the flatlock seams eliminate chafing and irritation. This is a SALEWA® Committed product that meets additional environmental and sustainability criteria.
