The Flare Ball jacket by Fith features innovative high-performance filling made from nanopolymer polyester fibers that convert sunlight and body heat into warmth, creating a 10-degree temperature difference in light.

This semi-permanent heating material is washable and offers the lightweight, high-bulk qualities of down. With water-repellent, windproof outer and lining materials, the jacket provides excellent heat retention, while ventilation zippers under the arms offer adjustable breathability for added comfort.
