Patagonia Boa Vest Kids M size, for 10-year-olds Kids often dislike sleeves that feel bulky, so layering didn't bother her, and the boa vest was surprisingly convenient. It's also good for adjusting indoor temperature. Although it says 10 years old, it can be used for ages 9-11. My daughter loved wearing it, so there's a feeling of wear. Please understand this before purchasing. Color: Light gray, close to white Pattern/Design: Solid Length: Mid-length Material: Boa Hood: No hood Season: Winter Color: White系 (White-based)
