Low weight, full performance—these ultralight insulated shorts deliver warmth, breathability, and mobility for demanding ski tours and cold-weather objectives.

Designed for efficiency on steep ascents and protection in shifting mountain weather, the Swisswool Piz Boè Shorts combine sustainable insulation with technical materials for reliable performance. The 60 g/m² Swisswool lining provides an exceptional weight-to-warmth ratio, keeping you comfortable without bulk—even when conditions turn damp. Paired with the wind- and water-resistant Pertex® Quantum outer, the shorts shield you from cold gusts and light precipitation while remaining soft, light, and highly packable.

Elastic Merino Airsolation stretch inserts at the sides and cuffs enhance breathability and freedom of movement, allowing you to skin, bootpack, and transition with ease. Full-length side zippers make it simple to layer the shorts on or off without removing your ski boots—ideal for changing temperatures and high-output days.

An athletic, close-fitting cut ensures efficient layering, while the adjustable waistband with an elastic insert maintains a secure, comfortable fit. Finished with Ortovox’s signature triangle stitching, the Piz Boè Shorts deliver a refined, functional design ready for fast-paced tours and deep-winter missions.
