The jacket features a quilted stitch design to retain equal distribution of the ThermoBall insulation. The outer fabric material is ripstop to add durability. Two hand pockets provide storage for essential items. The internal cuffs of the jacket are elasticated for superior warmth retention. ThermoBall Insulation ThermoBall offers the lightweight, warmth, loft and compressibility of down insulation but with the wet-weather insulating performance of synthetic. Developed in partnership with PrimaLoft, Thermoball insulation is produced as small balls of synthetic fibers that replicate the clustering properties of down, trapping heat within air pockets to retain warmth. In testing, Thermoball has been found to have the same warmth equivalent of 600 fill goose down.
