Breathable mesh material. Selling because it's outgrown. No snags or overlooked issues, as far as I can tell. The size selection doesn't have 160, for some reason, so I've selected S. I think it's a size S for adults. There's a small stain under the left armpit. It might come out with washing, but I'm selling it as is, at a special price (⋆ᴗ͈ˬᴗ͈)” - Brand: asics - Size: 160 - Color: Navy/White - Design: V-neck, short sleeves - Material: Mesh material Thank you for looking.
