New for the Autumn Winter 2020 Catalog. There's nothing worse than being cold whilst on the course. When the weather turns for the bitter this Autumn, look to this, the Techfill Jacket from Mizuno. It will provide protection from the cold in any virtual outdoor environment. Techfill maintains the jacket’s volume & function, while the Breath Thermo technology fabric captures escaping vapor to generate heat & return warmth to the body.
