Navy leg warmers for adults using BREATH THERMO technology. - Brand: Mizuno Pro - Product Name: Leg Warmers - Color: Navy - Size: Adult - Price: ¥2,420 Thank you for viewing. I purchased these last year for a junior high school student's practice, but they said they wouldn't be using leg warmers, so I'm selling them. They have been opened, but are unused and have been stored at home for a year. How about them for winter baseball practice, etc.? Length: Approximately 42cm
