Koster All-Weather Jacket - Men's

What Our Gearhead® Experts Are Saying:

"I’ve been using this as an everyday rain layer, and it’s been really reliable. It keeps water out without feeling heavy, and I like that I can stash the hood when I don’t need it."

Rainy days don’t change the plan, they just change what we wear, and the Koster All-Weather Jacket from Helly Hansen is built to handle it. Whether we’re heading out along the coast, navigating wet city streets, or dealing with steady drizzle throughout the day, it keeps us protected without adding unnecessary bulk. The clean design and classic feel make it easy to wear anywhere the weather turns.

HELLY TECH® Performance construction provides waterproof and breathable protection, helping keep us dry while allowing excess heat to escape. Fully seam-sealed construction blocks out moisture, while the packable hood stows neatly into the collar when skies clear. Adjustable cuffs and hem help seal out wind and rain, and multiple pockets—including a secure inner chest pocket—keep essentials organized and protected. Built with a PFC-free DWR finish, it’s designed for dependable use in wet conditions.
