I use these for my 6-8 year old boys, they are not too big and fit even the biggest boy (8 year old, 100lbs). ), about 4 feet tall), I've heard of kids swimming in BIG pinnies with holes too big for their arms or neck, I'd say that's your answer, I'll get on my feet and say fine for 5-10 year olds. .oh and they have good quality for soccer if you play rough for example and pull them in soccer. I don't know how long they'll last, they're just 'simple', but look at the price, what do you expect?
