Sizing Chart: 


Lightweight and airy, the Velox Zip Neck is specifically geared for high output activity and mountain training in hot weather. The Velox’s Libro™ stretch micromesh polyester material is selected for its effectiveness in these specific conditions. Highly air permeable, the fabric is created for maximum airflow and moisture evaporation. A wicking finish helps pull moisture to the surface to elevate the material’s performance.


The Velox combines simplicity in design with the Arc’teryx attention to performance focused details. The short stand up collar provides extra coverage without causing irritation at the larynx, and features a soft knit rear panel for comfort. The deep front zipper allows for rapid ventilation. Gusseted underarms provide exceptional ergonomic freedom, and flatlock construction at the seams minimizes chafing.
