Black and red diamond pattern swim shorts with a drawstring waist for adjustable fit. - Brand: arena - Color: Black/Red - Size: S - Design: Red diamond pattern on the sides - Style: Swim shorts - Features: Drawstring waist Thank you for viewing. These are arena swim shorts. They were my child's swim shorts when they attended Haruoka Swimming School. They are size S, but I think they run a little small. I bought S because I was worried about 160. They were used for about a year. Children grow up so quickly, so how about these for a spare pair, such as for a little while until they graduate from elementary school?
