Good
Used for six times and the inside of the lenses are damaged. Just rinsing them off with water and not rubbing with anything except my eyelids.

Did not seal well. Water leaks in
These are great goggles. Comfortable fit
Excellentes lunettes Ă prix abordable!
Tint wears off quickly
Unfortunately I can't recommend this product like many others from decathlon. Anti-fog layer stopped working after 3-4 sessions. Plastic itself is very soft and it is extremely easy to scratch eaven when you use soft cloth to clean it. I used it 2-3 times a week. The only good thing about this goggles is stylish look and adjustable nose gap.
Great
These are great Goggles have been using it for a while now and so far so good, keeps water out and clear. Would highly recommend these.
Very good for under water, great quality and very comfortable!

Patented innovation
Are you looking for swim goggles that are tailored to fit your face, completely watertight and that do not move as you swim, dive, or tumble turn? We bring you the answer in the B-FAST goggles with a nose bridge adjustment system that is simple and precise. This system lets you fine-tune the spacing of the 2 lenses, using either the screwdriver provided with the goggles or the built-in tool on the back buckle.
Fogging
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 depends on the skirts correctly fitting 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 precise nose bridge adjustment
How to adjust your goggles
These swimming goggles mold to the shape 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.
Lens tint
The color of your goggles should be suited to your swimming location and its lighting. If you practice outside or in a pool with harsh lighting, prioritize 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.
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
