It is not waterproof. when used in water, head gets wet.
Thank you for rating the baby mesh swim cap. Your feedback is important for us to improve our products year on year.
I apologize for the bad experience that you have faced with the swimming cap. There is no swimming cap which is water proof. All swimming caps get your hair and scalp wet. The purpose of wearing a swimming cap is to avoid your hair getting in your face as you swim and to give you traction in water. It is also used to ensure pool hygiene. Thus, even with this swimming cap, your hair would get wet inevitably.
However, if you are not happy with the product, I invite you to any of our Decathlon stores across India to have the swimming cap exchanged for a product that best fulfills your requirement. Our sales advisers will be more than happy to help you out in case you have any further queries.
I stay available if you have more questions. Have a good day!
