    Brand's answer :

    Hello Kumar,

    Thank you for rating the Adult diving and snorkeling mask. I apologise for the bad experience you have faced with it.
    Looking at the problem you have faced, it may be because the size of the mask does not fit your face, because of which, the snorkeling mask feels lose and water is seaping in. The perfect way to decide the size of your mask is to wear it without the belt, press it onto your face and create the suction effect. If the mask remains on your face for more than 5 seconds with the suction, then it is the right size for you.

    As for the product, I invite you to any of our Decathlon stores across India to have it exchanged for a product that best suits your requirement. You can ask any of our sales advisors at the stores to help you choose the best mask size, so that you will have a brilliant snorkeling experience.

    Do get back to me in case you have any further queries. Have a nice day!
