Not as comfy as I had hoped, but OK

The mask seems well made and easy to adjust. I swim in an outdoor pool, so the tinted lenses are great. I have used them 3 times so far. I find them to be uncomfortable after an hour. I wonder if the skirt around the nose area could be just slightly wider, it feels like it digs in a bit there, while everywhere else is very comfy.

Great alternative to traditional googles does not put pressure on the eye socket. Inexpensive too.

uv protection on clear or smoke only lens?

i bought the Active which the lens are smoke, not tinted. is the goggle still UV protected?

2nd purchase

Previous pair were fine until eventually the anti mist failed to work. I expect the same will happen again. Same problem I had with a pair of Zoggs previously. The anti mist appears to have a limited life span . I have yet to use this pair. Holidays only.

Excellent even for surfing

Very good, comfortable. I really need to know which UV protection this product gives. I checked the link in description under Instructions but it is not mentioned Can somebody help me to know UV protection level?

Ideal for those with deep-set eyes.

After trying several pairs of goggles in store, I found these to fit well and be comfortable. I have deep-set eyes and these are very comfortable and have never leaked to date.

Choice of size

Swim mask watertightness depends on correctly adjusting the silicone seals to fit the face shape. 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

Care precautions

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


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.



Storage instructions

After use, store the swimming mask in its case. Important: Important: do not touch the inner surface of the lenses as this could destroy the anti-fog treatment
