For nearly 150 years, technical outdoor brand Helly Hansen has been trusted by professionals around the world to create gear they can rely on in the harshest conditions. Rooted in a rich sailing heritage, the Norway-based brand merges technical performance with marine-inspired style. For Spring/Summer ’26, Helly Hansen introduces the new Koster 2.5L Jacket – a fully waterproof and breathable rain jacket that brings modern function to a classic nautical design.
Featuring HELLY TECH® Performance fabric construction, the jacket guarantees waterproof, breathable protection in a timeless design that’s ideal for everyday wear. It’s also highly durable, with a front zipper designed for easy removal and replacement – extending the product’s lifespan without compromising waterproof performance.
Additional features of the Koster 2.5L Jacket include an adjustable hood and elastic cuffs and bottom hem, and it’s built with recycled and certified fabric.
“Helly Hansen was founded nearly 150 years ago by a sea captain who wanted to protect his crew from the harsh Norwegian elements,” said Synne Alida Landbakk, Product Manager for Lifestyle at Helly Hansen. “That commitment to protection and performance has driven our innovation ever since and it’s why we continue to be trusted by professionals around the world today. With this jacket, we wanted to bring that trust and technical expertise into a design built for everyday wear, while also paying tribute to our maritime heritage.”
The Koster 2.5L Jacket will be available in both men’s and women’s specific designs in-store and online starting Spring 2026. To learn more about HELLY TECH® technology, please visit www.hellyhansen.com/en-gb.
