Mizuno black arm covers offer a comfortable fit. Breath Thermo is Mizuno's technology for warmth. ● Amazing heat generation: As the world's first artificial heat-generating material (developed in 1993), it boasts a higher heat generation capacity than wool. ● Dry and warm: When absorbing moisture and generating heat, it removes moisture from inside the clothing, making it less prone to stuffiness and providing a "refreshing warmth" that lasts. ● Retains heat: The structure traps warm air between the fibers, providing a thermos-like insulation effect. *For one arm only. - Brand: Mizuno - Color: Black - Logo: Mizuno logo - Type: Arm covers Thank you for viewing.
