Helly Hansen Mens Koster Sweat 1/2 Zip Navy

All the Details

Finished in classic Navy, the Koster Sweat has a refined, understated appearance that makes it easy to move between casual and smarter off-duty outfits. The minimalist design is complemented by a small contrasting HH logo at the chest, giving the piece a recognisable Helly Hansen finish without overpowering its clean look.

A half-length zip at the neckline allows the Koster to be worn zipped up for additional coverage or opened for a more relaxed appearance. The raised stand collar adds warmth around the neck and gives the sweatshirt a slightly smarter profile than a conventional crew-neck style.

Subtle horizontal seam detailing across the chest and body introduces structure while maintaining the streamlined aesthetic. Long sleeves, neatly finished cuffs and a straight hem complete the design, creating an uncomplicated layer that works particularly well throughout the transitional seasons.

Wear the Koster Sweat 1/2 Zip over a T-shirt with jeans and trainers for an easy weekend combination, or team it with chinos and casual boots for a more polished look. Its classic Navy colouring also makes it particularly easy to layer beneath gilets and jackets when cooler weather arrives.

Comfortable, versatile and deliberately understated, the Koster is an ideal choice for anyone looking for a casual layer with a slightly more refined finish.

Clean, versatile and easy to layer, the Helly Hansen Koster Sweat 1/2 Zip brings a smart edge to everyday casual dressing.
