Long Sleeve Crew Neck Side Zip Top

A wardrobe foundation with an unexpected edge. The LS Crew Side Zip Top starts with a clean crew neckline and a slight A-line body, then breaks convention with two functional zippers set into each side seam, giving you the option to wear it fitted and closed, or vented and relaxed.

Made from the same 350gsm modal-poly blend as the rest of the collection, it's soft against the skin with enough structure to hold its shape through a full day of wear. The side zippers are finished with fabric binding rather than exposed tape, so there's no metal rubbing against your hip, and the pulls carry no visible branding for a clean, considered look.

Every J. Strom piece is cut from the same fabric in the same solid black — mix and match any top, jacket, or bottom in the collection and everything matches, every time.
