Description

Specifically designed to keep the body cool during high output training in hot weather. The Actinium is made from Arc’teryx Viente™ fabric. Exceptionally air permeable, Viente™ is an ultralight, moisture wicking polyester micromesh. An anti-microbial treatment helps control odours.

RAPID TRANSIT

Every inch of the Actinium’s design is built for speed. The relaxed fit is comfortable and helps maximize airflow for more effective cooling and evaporation, and strategically placed flatlocked seams prevent chafing on long trail runs or extended training sessions. Articulated patterning is shaped to fit and move with the body, and gusseted underarms extend freedom of movement.
