Himalaya Yulong High-Altitude 800FP Water-Repellent Goose Down Jacket

The Himalaya Yulong Down Jacket is a professional-grade thermal outer layer engineered for high-altitude expeditions and extreme cold environments. Inspired by the rugged conditions of the world’s highest peaks, this jacket serves as a technical shield against wind, snow, and plummeting temperatures. Built with premium materials sourced from the "Golden Down Belt," it offers an elite warmth-to-weight ratio for mountaineers, hikers, and outdoor enthusiasts who refuse to let the weather dictate their journey.

Key Benefits

Elite 800+ Fill Power:** Sourced from the 45° North Latitude "Golden Down Belt," the insulation provides exceptional loft. This high fill power ensures maximum heat retention by trapping a deep layer of air while remaining incredibly lightweight and compressible.

95% Premium White Goose Down:** Featuring a high concentration of down clusters rather than feathers, this jacket provides superior thermal efficiency. The 220g fill weight offers a thick, pillowy barrier that maintains core temperature even in sub-zero alpine conditions.

Level 4 Water-Repellent Finish:** The specialized outer shell is treated to achieve Level 4 water resistance. This allows the fabric to effectively shed light rain and melting snow, preventing moisture from compromising the down’s loft and keeping you dry during sudden weather shifts.

Windproof & Snow-Ready Construction:** Designed specifically for snow mountain environments, the high-density fabric and specialized baffling work together to block biting winds and prevent heat leakage, making it an essential piece for high-altitude trekking.

Advanced Moisture Management:** While the exterior repels water, the internal structure is designed to remain breathable, ensuring that active users do not overheat during strenuous climbs.

How to Use

To maximize the thermal performance of the Himalaya Yulong jacket, use it as your primary outer layer in a traditional three-layer system. Pair it with a moisture-wicking base layer and an insulating mid-layer for temperatures well below freezing. For high-altitude use, ensure the hem and cuffs are adjusted tightly to seal in body heat. When transitioning from a packed state, give the jacket a vigorous shake and allow it to hang for 10–15 minutes to let the 800FP down fully loft before heading into the cold.

Care & Safety

To preserve the water-repellent coating and the integrity of the goose down, avoid frequent washing. If cleaning is necessary, use a specialized down detergent and a front-loading washing machine on a gentle cycle. Tumble dry on low heat with clean tennis balls to restore loft. Store the jacket hanging in a dry, well-ventilated area; avoid leaving it compressed in a stuff sack for long periods, as this can damage the down clusters. Keep away from open flames or high-heat sources.
