Lightweight warmth • Water Resistant: Partially blocks rain/snow to increase breathability. • Insulated: Insulation traps hot air for reduced heat loss and increased warmth. • Bluesign® Approved Fabric: Standard for environmental health & safety in the manufacturing process. • Quilting throughout body • ThermoBall™ offers the lightweight loft, warmth and compressibility of down with the wet-weather insulating performance of synthetics • Ultralight, packable synthetic-insulated parka retains warmth, even when wet • Internal elastic cuff • Fixed hood • Two secure zip hand pockets • Exposed center front zip • Internal waist adjustability • Embroidered logo at left chest and back right shoulder • Internal media pocket with media loop • Fabric: 30D nylon tafetta with Thermoball insulation • Fabric: Shell: 100% nylon 30D -- • 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 .
