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

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

Perfect fit for my 6yr old boy. He loves that they are nylon.

Awesome, grandson loves them!

The boys like these underwear

My grandson loves them, they give him self confidence

My 4 year old loves these

My son is obsessed. They are so comfy and soft

Bought these. for our Great Grandson. He loves them
