The incredibly lightweight Helium Hybrid Jacket is the most versatile down jacket you can own. Perfect as a second layer under a shell or down jacket, but also great to wear on its own. Stretch jersey side panels and sleeves guarantee complete freedom of movement. Windproof, with a Double Water Repellent outer layer, it effectively protects against wind and moisture, and packs down to a very small size. Insulation made from top-quality duck down and feathers, responsibly sourced and compliant with the "Track My Down®" program, guarantees warmth. It's perfect for all outdoor activities.
