Definitely size up. got a medium which is what my son normally wears but once he tried them on at home they were wayyyyyy too tight

These are wonderful for my 4 year old. He loves the bright patterns and characters. Fit is great and material helps keep him cool.

I got these for my son based on the size chart. They are very tight on him. He can’t wear them because he can’t pull them up or down himself. Unfortunately we can’t return them because they’ve all been washed before first wear.

I have ordered twice a size 10 thinking they made a mistake they sent me size 10 xL again which is way to big for my son which wears regular size 10. Size 10 xl is for husky boys. Very misleading

My nephew raves about material & comfort!

Great fit. Grandson loves them !

Looks just like the picture. Sizing is spot on, and the quality is above excellent.

Great quality exactly what I hoped for

Good price, gifted so don't know if ok.

My son is obsessed. They are so comfy and soft
