13oz Oxford Cloth Work Overshirt IHSH-423-CAM - Camel
US$325.00
Pickup currently unavailable
New for Fall/Winter ’25—our work overshirt, cut from a hefty 13oz Oxford cloth. Woven with double warp and weft yarns, the intricate plain weave of this fabric creates a heavily textured pile that is soft, robust and very comfortable to wear. Reactive-dyed to ensure a fade-resistant colour, the shirt is finished with tonal stitching and buttons for an understated, clean appearance.
Designed as an overshirt, this cut is an ideal winter layering piece, worn either as an outer or mid layer. Like our traditional work shirt, the cut includes classic patch chest pockets (complete with a pen holder) and button fastenings throughout. Where it differs is in its looser fit, straight hem, and split side-seam gussets, which are more characteristic of our mechanic shirt cut. Wear true to size for layering or a casual relaxed fit, or size down for a more fitted silhouette.
