Developed in partnership with Primaloft, Inc., ThermoBall is a revolution in insulation technology. Unlike traditional continuous-filament synthetic insulation, the small, round PrimaLoft synthetic-fiber clusters closely mimic down clusters, trapping heat within small air pockets to retain warmth. Independent clo testing by Kansas State University has shown that ThermoBall has warmth equivalent to 600 fill goose down. As a result, ThermoBall can offer the lightweight warmth and compressibility of down with the wet-weather insulating performance of synthetic insulation.
PrimaLoft® Silver Eco Earth-friendly insulation created for performance and comfort. Eco insulation technology combines a minimum of 50 percent recycled material with standard PrimaLoft® fibers to create a high-loft, thermally efficient insulation. PrimaLoft® Silver Eco is lightweight and water resistant with superior softness to keep you dry and comfortable.
PrimaLoft® Gold is the ultimate microfiber insulation. Ultra-fine fibers are specially treated in a patented process and then combined into an insulating core that is incredibly soft, lightweight and water resistant. PrimaLoft® Gold absorbs three times less water, is 14 percent warmer when dry and is 24 percent warmer when wet than competitive insulation.
PrimaLoft® Silver The perfect combination of high-performance insulation and value, this technology combines ultra-fine and multi-diameter fibers for specific performance characteristics. The specially treated ultra-fine fibers help to form a water resistant insulating structure, while the multi-diameter fibers help to build loft.
