Thank you for looking.

These were worn by my son when he was a student.

　The tag has faded due to washing.
　Likely size L. Name written on tag.
・Half Pants
　① PUMA (Gray) Size O
　　Several snags, name written on tag.
　② PUMA (Red) Size O
　　Name written on tag.
　③ adidas (Navy) Size S
　　Waist elastic has deteriorated.
・Windbreaker (Lightweight) Asics
　Size L

All were worn during the same period.
How about using them for practice wear?
