Speedo Boy's Swimsuit Jammer Begin to Swim Solid

Tiene cordon en la cintura para ajustar?

My son is 10 years old and weighs 68 lbs. Would this Black 10 fit him?

What is the length from crotch to top of waistband in either the size 6 or size 7? Size 5 was too short at stomach for 7 yr old.

What age can wear these?
