Officially recognized as the warmest jacket on the planet, it outperforms legendary brands like Canada Goose and Arcteryx. Key features include a patented WarmLife technology with a metallic nano-coating that reflects 100% of your body's infrared heat back to your skin, elite goose down (800-fill power) for superior insulation, and complete wind and moisture impermeability. Size L, in brand new condition. Please feel free to ask any questions. The price is negotiable and discounts are possible.
