Built for demanding ski tourers who rise before dawn and move fast through steep, variable terrain, the Ortovox Swisswool Piz Boè Shorts deliver lightweight, breathable insulation without compromising mobility. Their 60 g/m² Swisswool fill provides an exceptional warmth-to-weight ratio, maintaining insulation even when damp while regulating moisture during high-output ascents. Wrapped in PERTEX® Quantum recycled polyamide, the shorts block wind, shed light moisture, and stand up to rough wear with impressive abrasion resistance.

Elastic Merino Airsolation stretch inserts at the sides and cuffs enhance breathability and allow the shorts to move freely with every kick turn, scramble, and skin track switchback. Full-length side zippers make it easy to layer up or strip down on the fly, while the adjustable waistband with elastic insert ensures a stable, comfortable fit. Designed with an athletic silhouette and modern triangle-pattern stitching, the Piz Boè Shorts pack down small yet deliver big performance when temperatures drop or conditions turn unpredictable.
