Decathlon Kid's Pool Mask with Clear Lenses Swimdow Pink

Hello Nat,
Please have a look below on how to choose the right fit.
Choice of size:
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).

How to adjust your mask:
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 will optimize the grip and comfort of the mask.
Thank you for using Q&A
