Designed for demanding ski tours and mixed alpine missions, the Swisswool Piz Boè Vest delivers an exceptional balance of warmth, packability, and mobility. The vest uses 60 g/m² Swisswool insulation, a sustainable and regionally sourced natural fiber that retains warmth even when damp and regulates moisture for a consistently comfortable microclimate during high-output ascents. A lightweight Pertex® Quantum outer material—made from recycled polyamide—adds windproofing, high abrasion resistance, and light weather protection without sacrificing softness or compressibility.

For enhanced mobility in steep or variable terrain, Merino Airsolation stretch inserts are integrated along the sides and back. These breathable panels improve airflow, support temperature regulation, and allow the vest to move seamlessly with the body through kick-turns, skinning, and technical climbing. An elastic, pre-adjusted hood and carefully positioned chest pockets round out the vest’s alpine-focused design, making it an ideal midlayer or outer layer depending on conditions. The athletic cut ensures a close, efficient fit that layers cleanly under shells or over base layers.
