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.


B-FAST NABAIJI goggles are training and competition goggles approved by FINA (international swimming federation).


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.
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 ageing anti-fog coating and increases the lifetime of your goggles.


We recommend:
- rinsing your goggles (only if necessary) by simply dipping them in water
- avoiding directing powerful jets of water at the inner surface of the lenses.
- storing the goggles in their case after each session to prevent damage to the lenses (on the inner surface as there is an anti-fog coating and on the outer surface to prevent scratches)
- not exposing them to temperatures of over 60°C


The watertightness of the swimming goggles is dependent on the proper fit of the skirts with the shape of your face.
Before purchase, we advise you to do the "suction" test without the strap.
If the goggles stay on the face by themselves via slight suction, the product will be watertight during your swim. They also locate any points of discomfort of the model on your face.
One-size model with micrometric nose bridge adjustment


Swimming goggles suited to the shape of your face do not need to be worn tight.
Goggles that are too tight can cause discomfort, leave marks and sometimes even let in water.
There is no need to press on the lenses with your hands, a slight suction effect is generally enough for most swimming sessions without letting water in.
The straps should ideally sit 2 to 3 cm above the ears.
This is the best position for hold and comfort.


The colour of your goggles should be suited to your swimming location and its lighting.
If you practice outside or in a pool with harsh lighting, prioritise goggles with smoky lenses to limit the glare for greater comfort.
If, however, the pool is quite dark with low lighting, winter evenings for example, use clear lenses.
The B-FAST swimming goggles are available in different lens tints.


Complies with standard: Q/BT 4734 - 2014, all the Nabaiji swimming goggles protect against harmful UVA and UVB rays when used normally, regardless of the lens tint.
Looking directly at the sun is dangerous and can lead to irreversible eye damage.
