Callum | Men's Relaxed-Fit Ribbed Quarter-Zip Jumper
Product Description
The Callum Men's Relaxed-Fit Ribbed Quarter-Zip Jumper is your go-to choice for effortless, elevated layering through the colder months. Cut with a relaxed yet structured silhouette in a dense ribbed knit, finished with a stand collar and quarter-zip neckline, it's perfect for men who want a clean, confident look that still feels easy to wear.
Why You'll Love It
- Quarter-Zip Collar: Gives you the option to adjust the neckline for extra warmth or a more open, relaxed look.
- Dense Ribbed Knit: Holds its shape wash after wash, so it stays looking sharp season after season.
- Relaxed, Roomy Fit: Sits easily on the shoulders with plenty of room to layer over a tee without ever looking boxy.
Perfect For
Layering over a plain white tee for a laid-back weekend look, wearing under a wool overcoat on the daily commute, dressing up with dark chinos and clean trainers for casual Fridays, or pairing with tailored trousers for a relaxed dinner with friends.
Care Instructions
- Hand wash or machine wash on a cold, gentle cycle.
- Do not bleach.
- Lay flat to dry to help the ribbed knit keep its shape.
- Use a cool iron if needed and avoid pressing directly over the zip.
