Fit, function, fabric – the Cormac Heavyweight is built for freedom of movement and high-output comfort in colder conditions. Essential thermal performance, moisture management, and softness come from its Phasic™ AR II material. An engineered polyester made with wicking fibres, it provides stretch, sun protection, and is stitched for a smooth finish next to the skin. The ergonomic design and articulated patterning remove restriction, and the clean fit layers easily and wears comfortably on its own.

The Cormac Heavyweight Shirt LS was previously the Motus AR Crew LS.
