Hi Jeremy,

First of all, thank you very much for your feedback on our products.

I'm also really happy that you are satisfied with our googles for your exercise during this difficult time. I have forwarded this to our product engineers for them to take this into account for their next product design.

Again, thank you for the feedback, don't hesitate to write to us how you feel on our other products.



Excellent goggles

Popped in to replace my swimming goggles and bought with confidence. I wasn’t disappointed as these exceeded my expectations. Excellent pair. Really impressed.

No matter what I do can't get them to stop leaking. Based on plenty of good reviews maybe it's just the shape of my head but admittedly haven't the same issues with other brands. Pretty disappointed as generally a huge fan of Decathlon own brands.


Great product!

Good value, good price

My daughter swims in a County swim team and goes through many goggles... she needs a pair she can trust and we have found this brand to be perfect for her needs (even her coach recommended the brand).

Were recommended these goggles in the Edinburgh store as good for anti fogging but have been sadly disappointed - have fogged up pretty much since day one and also have some form of residue on the inside of the goggles which does not come off.

Dear Jamie,

Thank you for your recent feedback. It sound to me that you have probably taken used / ex display model from the store? I personally have been using two of them for my swimming training in last few months and haven't discovered any issues with the lenses or the anti fogging treatment.

Please do not hesitate to bring back your pair and we will be happy to exchange it for new one or other model if you prefer.

Once again apologies for any inconvenience caused.

Kind regards,

Hello Omkar,

Thank you for rating the swimming goggles. Your feedback is important for us to improve our products year after year.

I apologize for the bad experience that you have faced with the swimming goggles. I notice that you have a sealing problem on the goggles you bought. Before purchasing , we recommend to try the goggles on the face of the user and to the test the "sucker" property of the goggles to check if it matches the morphology of the face.  The sales manager can introduce you in greater detail and help you to choose the model and the most suitable size. If the vacuum test is OK, it means that the product is adapted to the morphology of the face and that tightness is guaranteed. Here is the video that can help you with choosing the goggles-             

In case you have any other queries, I stay available. Have a good day!

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 re-form. 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 that reactivates an aging anti-fog treatment and makes your goggles last longer.

Choice of size

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. This also enables you to spot any areas of discomfort or annoyance when the model is on the face. 1-size model with 3 interchangeable nose bridges

How to adjust your goggles

These swimming goggles mold to the morphology of your face without needing to be excessively tight. Goggles that are too tight can cause discomfort, leave marks and even create water inlet holes. It is not necessary to press against the lenses with your hands, a light suction effect is usually enough for swimming sessions without water inlet holes. The straps ideally should rest 0.8" to 1.2" above your ears. This position will optimize the grip and comfort of the goggles.

Care - precautions

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 140°F DO NOT TOUCH/RUB THE INSIDE OF YOUR LENSES

Lens tint

The color 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, prioritize smoke lenses for greater comfort and to limit the glare. If, however, the pool is quite dark with low lighting, winter evenings for example, use clear lenses. The BFIT swimming goggles are available in different lens tints.

Uv protection

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.



Product testing

The Nabaiji swimming goggles comply with the EPI regulation 2016/425. Our products are tested and approved by independent laboratories. Goggles intended for swimming at the surface

Storage instructions

After use, store the goggles in their case. Important: Do not touch the inner surface of the lenses as this could destroy the anti-fog treatment
