Get the Layered Look Without the Extra Bulk
Create a crisp layered look without extra warmth or bulky layers — breathable cotton denim, 1.76 oz lightweight construction, extended shoulder panels, machine washable.

Why Is This Collar Perfect for You?
✔ Soft, breathable denim: Made from soft, breathable 100% cotton denim, this lightweight collar provides a structured shirt look without the heat or restrictive feel of a full base layer. At 1.76 oz, it adds minimal weight while staying comfortable throughout the day.
✔ Secure fit that stays in place: Four functional buttonholes allow for an adjustable fit, from a relaxed open neckline to a fully buttoned look. Extended shoulder panels help keep the collar anchored and lying flat under clothing, reducing slipping, bunching, and constant readjustments.
✔ Durable and easy to care for: Reinforced stitching helps the collar maintain its shape through daily wear and washing. It is machine washable, and a quick warm iron can restore a crisp finish, making it easy to wear across professional, dressy, and smart-casual outfits.
