The Tamar Quarter Zip
Named after the River Tamar — the natural boundary between Cornwall and Devon — it reflects a sense of balance and quiet definition. A familiar shape, refined through detail.
Cut from a heavyweight jersey, it has structure without feeling restrictive. The funnel neck and metal zip keep things clean and functional, while herringbone taping and reinforced finishes are built to stand up to regular wear.
There’s weight to it, but it moves easily.
Comfortable, without feeling casual.
A contrast stripe runs across the chest and sleeves — subtle, but enough to give it character. The Biddle & Byre embroidery sits on the chest.
Made to be worn — easy to put on, and kept on through the day.
100% ringspun cotton.
