Mizuno Men’s Breath Thermo Mid Active Jacket

Almost too light and flexible to be a jacket – only possible through the use of Mizuno’s heat generating Breath Thermo yarn. Perfect for cold, clear conditions and thin enough to wear under a waterproof. Breath Thermo® yarn captures escaping body heat and, through a patented physical reaction in the yarn, generates heat-warming the body.
