Mizuno Breath Thermo Kids' innerwear, size 120. I believe this size is no longer sold. If the long hem doesn't bother you, it can be worn from around 3 years old. Because it's Breath Thermo, it generates heat with a small amount of sweat. You'll feel the difference in warmth just by wearing one layer. Recommended for winter sports and outdoor activities. - Brand: Mizuno - Marked Size: 120 - Color: Black - Purpose: Innerwear - Features: Breath Thermo - Condition: Small pills present.
