Pool mask SWIMDOW - Clear lens - One size - Blue black

The appearance of fogging 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 provide an anti-fog marker that reactivates an ageing anti-fog treatment and makes your goggles last longer.

The colour of your goggles should be suited to your swimming location and its lighting. If you swim outdoors or in a swimming pool with bright lighting, prioritise smoked 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.

Complies with standard QB/T 4734-2023; all 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.

A swimming mask that fits the shape of your face does not need to be excessively tight. A mask that is 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 2-3 cm above your ears. This position with optimise the grip and comfort of the mask.

Swim mask watertightness depends on the silicone 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. This model comes in size S (narrow faces) and size L.

We recommend: - rinsing your mask (only if necessary) by simply dipping it in water - avoiding directing powerful jets of water at the inner surface of the lenses. - storing the mask in its case after each session to prevent damage to the lenses (on the inner surface there is an anti-fog coating and on the outer surface to prevent scratches) - not exposing it to temperatures of over 60°c DO NOT TOUCH/RUB THE INSIDE OF YOUR LENSES
