Named after the River Tamar — the natural boundary between Cornwall and Devon — the Tamar Quarter Zip is a timeless everyday layer with a sense of balance, place and understated character. Made from heavyweight 100% ringspun cotton jersey, it has a structured feel without being restrictive. The funnel neck and metal quarter zip give it a clean, functional finish, while herringbone taping and reinforced details are designed to stand up to regular wear. A contrast stripe runs across the chest and sleeves, adding subtle character without feeling overdone. Comfortable, easy to layer and made to move with you, it’s the kind of piece you can throw on in the morning and keep on through the day. Finished with Biddle & Byre’s understated embroidery at the chest. Size Guide The Tamar Quarter Zip is designed with a comfortable everyday fit, making it easy to wear on its own or layered over a T-shirt or polo. We recommend choosing your usual size. If you prefer a more relaxed fit, or plan to wear it over heavier layers, you may wish to size up.
