The North Face ThermoBall™
The North Face ThermoBall™ is this season's major breakthrough in insulation technology. Powered by PrimaLoft®, ThermoBall™ insulation has been designed to mimic the fabulous natural insulating properties of goose down, but with the added benefit of being able to insulate just as effectively when it is wet.
The North Face ThermoBall™ consists of small round clusters of synthetic fibres that mimic goose down as opposed to traditional synthetic insulation that consists of linear continuous filament fibers. ThermoBall™ clusters have more plentiful air pockets to trap warm air very effectively, retaining phenomenal warmth. ThermoBall™ conforms to the shape of your body to increasing its warmth-maintaining ability even further.
"The North Face Men's ThermoBall™. Never one place, always one jacket"
Independent CLO testing by Kansas State University has shown that The North Face ThermoBall™ insulation has the equivalent warmth of 600 fill goose down. As a result this collection of The North Face Men's and Women's ThermoBall™ Jackets and Gilets offer the warmth, loft, low-weight and compressibility of a down insulated jacket along with the bonus ability to maintain insulation in wet weather.
Built to be highly water- and wind-resistant, a Men's ThermoBall™ Jacket is the 'Go-To' choice for a multitude of outdoor activities, from skiing to hill walking. Trust The North Face ThermoBall™ to keep you warm and comfortable in cold dry or damp conditions. And when a storm blows in, wear your new ThermoBall™ Jacket as a super-warm mid-layer underneath your waterproof jacket.
