The watertightness of the swimming goggles is dependent on the proper fit of the silicone seal with the shape of your face. Before purchase, we advise you to do the "suction" test without the strap. If the goggles hold on your face by themselves with slight suction, the product will be watertight during your swim. This allows you to see if the size is too tight or too big according to how they feel.

You should: - rinse your goggles after use - put them in a box between each session to prevent any contact with the lenses (inside where the anti-fog coating is located, and outside to avoid any scratches that may impact your visibility). NEVER TOUCH/RUB THE INSIDE OF YOUR LENSES.

The appearance of fog depends on several factors, the difference in temperature between the body and the water, humidity levels, etc. Wear due to friction is one of the main causes. If your goggles fog up, dip your lenses in the water and a protective film will reform. Be aware that after a certain amount of time it is normal for the performance of the anti-fog coating to be diminished. We offer an anti-fog marker which reactivates the anti-fog coating and increases the lifetime of your goggles.
