Thank you for viewing. This is PUMA training wear. It's thin, so I think it's good for this season. The quality tag has been cut off, but it's a smooth fabric and stretchy. It's not the "shaka-shaka" type (windbreaker sound). The size is S, and it's the type without a drawstring, but it stretches well. I think it's also good as an inner layer in winter. Thank you.
