My son is a size 8 and these medium fit him well (see picture). They have a yellow tie inside which can also be tightened. He said they were so comfortable that he just left them to relax. They also have an inner lining, which is what I've been looking for in swim trunks.

Excellent swimming trunks! My son likes to wear them. They dry quickly and look very good. They have a mesh lining on the inside and feature drawstrings at the waist and pockets. My 10 year old son weighs 60 pounds. And the height of 52 inches and medium fit perfectly.

Nike is our son's favorite swimwear brand. He's slim, so most brands have big waists, but we have no problem with Nike trunks. The fit and style was perfect and they have held up well throughout the watersports summer.

All in all these are great shorts. Love the fact that they are Nike, they are the perfect length, they have a mesh lining and a drawstring waist. have noticed quality issues so far but will update when I do.

I bought several pairs of swim shorts for my son this year and they are amazing! Nike's simple blue design is perfect for boys' swim shorts. The material is very comfortable, soft and well made!

My 13 year old loved the shorts but could barely wear the large ones. It's very thin, not too big. I want to buy XL but it's sold out.

This article is very small. I bought a medium size. My son is only 7 I increased the size by 2 I can't even get them over his ass and I bought them in 3 colors and I'm having a hard time getting them back

I bought these shorts for my 7 year old who is tall and skinny and they fit great! Usually shorts are too loose or tight around the waist and shorts are too short but these are perfect! They have a drawstring to tighten the waist even more if needed. The length is mid-knee, they are slightly baggy (not straight and tight like surf shorts). They have 2 side pockets. My son loves the way they fit and look!
