The Princeton Shirt Jac takes the utility of an insulated overshirt and gives it a more elevated outerwear presence. It is built for the in between moments: early starts, long shifts, travel days, and nights when a hoodie is not enough but a heavy jacket is too much.
A structured collar, button cuffs, and clean chest pockets keep the silhouette sharp, while oversized internal stash pockets give you practical storage without loud external bulk. The relaxed fit makes it easy to layer over a base layer while still holding a tailored line.
Key features
• Hybrid shirt jacket design with insulated warmth

• Relaxed true to size fit for base layer compatibility
• Clean utility styling for work, street, and travel
