FeatherCore 3.0 — Machine Washable, No Clumping
Encapsulated down fibers maintain loft and warmth after multiple washes. Unlike ordinary down, it dries fast and stays fluffy, solving clumping and flatting issues.

Sourced from 45°N premium down regions, FeatherCore 3.0 achieves 800 fill power with 1500mm clarity and <0.3% impurities, delivering lasting warmth with less weight.

Zoned Insulation — Warmth Without Bulk
Extra fill at the waist and hem keeps core areas warm, while slimmer fill at the shoulders prevents a bulky look. Designed for warmth that complements body lines.

Ultra-Light & Packable — Built for Everyday Travel
Weighing just ~250g, this vest is 21.8% lighter than standard down vests. Easy to layer, easy to pack, and perfect for versatile styling.

Water-Resistant Finish — Everyday Weather Protection
With a water-repellent coating and abrasion resistance up to 18,000 cycles, the fabric resists drizzle, stains, and daily wear.
