This hybrid inner down vest pairs a high-density gridded nylon shell filled with 95% goose down at 750 fill power with wool-blend knit sleeves, creating a layering piece that balances insulation and freedom of movement. The shell features a proprietary water-repellent treatment and far-infrared heat-retention finishing, while the stand collar adds wind protection without bulk. A signature figure-eight panel construction on the front and back defines the silhouette and keeps the streamlined fit close to the body. Two front pockets provide practical storage and additional warmth retention.
