Mizuno Mizuno Golf Breath Thermo Insulated Blouson Thin Down Size: M Color: Pink Worn 2-3 times only for winter rounds. This insulated blouson incorporates Mizuno's unique Breath Thermo, a heat-generating material, in the filling. Breath Thermo, a high-performance synthetic fiber that generates heat by reacting to water vapor and moisture, is mixed with polyester fiber, also known as artificial down, creating a jacket with excellent cold protection. You can use it with a light down feel. This is a used item, so there may be minor scratches or stains that I may have overlooked. Please refrain from purchasing if you are concerned. * When shipping, it will be folded small.
