Helly Hansen started in 1877. In the 20th century, Helly Hansen made several breakthroughs in product development to complete the layering principle today known as the 3-Layer Systemâ„¢. The original fleece, the fiberpile, was developed in 1961 and has been perfected for almost 50 years since. This new insulation layer was warm, lightweight and fast-drying, ideal for wearing under the protective layer. In 1980, the Helly Tech technology was launched, using both hydrophilic and microporous technology, which meant the apparel was both waterproof and breathable for high-activity outdoor sports. Helly Hanson products are used by world-class sailors, skiers, and adventurers. Products offered include jackets, pants, base layers, fleece and mid-layers, sweaters and knits, shirts and polos, t-shirts, shorts and beachwear, footwear, bags, and life jackets.
