Technical Information

Are you looking for swimming goggles that are tailored to fit your face, completely watertight and that do not move as you swim, dive or tumble turn? We have the answer with B-FAST goggles thanks to a simple micrometric nose bridge adjustment system. This system lets you fine tune the spacing of the two lenses, using either the screwdriver provided with the goggles or the built-in tool on the back buckle.
NABAIJI Swedish swimming goggles are FINA (International Swimming Federation) approved training and racing goggles.
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.
The colour of your goggles should be suited to your swimming location and its lighting. If you swim outside or in a swimming pool with bright lighting, you will benefit from smoke-tinted or mirror finish goggles. Your comfort of swimming will be greater. In comparison, if the swimming pool is darker with low lighting, during winter evenings for example, you will prefer transparent or slightly tinted lenses. B-Fast goggles are available in different lens tints.
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. THIS MODEL IS ONE SIZE ONLY BUT HAS PRECISE NOSE BRIDGE ADJUSTMENT.

Looks very nice and fits nicely on my face, the only problem is it steams up every time and i have to stop and clear it every two lengths. Followed staff advice of using the fog marker but still no luck.

Cannot refund anymore so a waste of £17, what a shame.

Response of the brand
Hello Rajeev,

Thank you for rating the B-Fast swimming goggles. 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 goggles. I see that you have a sealing problem with your goggles, as you say that water enters them, it is due to the sizing issue. When you purchase your goggles, you need to first try the suction property, that is, put the goggles around your eye socket without the strap on and let it stay for at least 4 seconds without falling. If this happens, then the swimming goggles are the right size for you.

Nevertheless, I invite you to any of our Decathlon stores across India to have the goggles exchanged for a product that best suits your requirement. Our sales advisers will be more than happy to help you in case you have any queries.

I stay available if you have further questions. Have a good day!
