The flexible fit with an elastic band it adapts perfectly and grow with. My son with just under 4 years, she fits perfectly and he is still able to wear next year at least. The fabric dries very quickly thanks to 100% nylon, is beautifully light and soft. The incorporated terry sweatband also contributes to comfort and no pressure points. Ears and neck are well covered. So must be a good sunscreen Cap, I can recommend it without any restrictions.
