HELLY HANSEN Women´s Koster Jacket

Master the elements in style with the HELLY HANSEN Women´s Koster Jacket, a masterclass in versatile, all-weather protection. Engineered for the modern woman who demands performance without compromising on aesthetics, this jacket is your ultimate shield against unpredictable weather, whether you´re navigating coastal paths, enjoying a day on the boat, or commuting through the city. Its clean, classic design makes it a go-to piece for any outdoor adventure or daily activity where staying dry and comfortable is paramount.

The Koster jacket is built to perform, offering complete protection from wind and rain. At its core is the renowned HELLY TECH® Protection fabric technology, a dual-layer system that is fully waterproof, windproof, and breathable. This intelligent construction ensures that rain, spray, and wind are locked out, while allowing internal moisture and excess heat to escape. The result is exceptional thermal comfort, keeping you dry from the outside and perfectly regulated on the inside, no matter your activity level. For an impenetrable defense against moisture, all seams are fully sealed, leaving no entry point for water during even the most persistent downpours. A Durable Water Repellency (DWR) treatment on the outer fabric provides the first line of defense, causing water to bead up and roll right off.

Designed with the active woman in mind, the Koster jacket offers superior comfort and freedom of movement. The lightweight, stretch fabric moves with you, ensuring you never feel restricted during hikes, sailing, or simply reaching for your essentials. The interior features a quick-dry, comfortable lining that feels soft against the skin and helps manage moisture for all-day wearability. The women´s specific, regular fit is thoughtfully tailored to provide a flattering silhouette while still allowing ample room for layering a fleece or sweater underneath in colder conditions.

Functionality is seamlessly integrated into its sleek design. A fully adjustable, stowable hood can be quickly deployed for immediate protection from a sudden storm and then neatly packed away into the collar for a streamlined look when the sun returns. The high-quality YKK® front zipper is protected by a storm flap for added weather resistance, and an anti-chafe chin guard prevents irritation when the jacket is fully zipped. Fine-tune your fit and seal out drafts with the one-hand adjustable drawcord at the hem and the adjustable cuffs. Two zippered hand pockets provide secure storage for your phone, keys, and other essentials, keeping them safe and dry. Lightweight and highly compressible, the Koster jacket is easy to pack into a daypack or travel bag, making it the perfect companion for any journey.
