A full face snorkel mask covers your entire face. It allows snorkelers to breathe using both their nose and mouth which is a much more natural way of breathing for most people.It is easier to breath than a traditional snorkel.

Please rest assured.Any mask of our store has been tested.  As long as you wear the mask correctly and make it fits properly,it won't leak. Make sure there aren’t any loose strands of hair or facial hair under the mask skirt since this can prevent a tight seal from forming and cause leakage.

The skirt of our mask is made of soft and flexible silicone, so in most case, it's comfortable for you to wear. Mostly, the uncomfortable issue are due to the unproper use, such as over-tighten the strap,. If you wear it properly, but still feel uncomfortable, it's a wrong fit. Here are the signs that the mask isn't fit: One, the bridge of your nose is pressed up against the mask.Two, Masks has narrow space in the nose area. Three, you rely on over tightening the straps to enforce the mask’s seal. If you meet these issues with our product, please contact us right away and we will help you with these to make you satified.

Unlike traditional snorkels, you don't need to 'purge' or clear your snorkel of water when resurfacing. These have a Dry Top system, so a plastic ball moves to close the tube when submerged. This stops water from entering the tube.
As soon as you resurface, the ball lowers and the tube is open to breathe air through again.

You Mask will also need to be washed regularly to remove dust, dirt, salt and oils from your skin. Once your mask is clean you can treat it with a de-fogging agent so that it doesn’t fog up.

If you feel you have a mask that fits properly then adjust the straps for a comfortable fit but do not over-tighten. Sometimes over tightening can cause a leak and is not as comfortable too. Also, make sure to clear your hair from your face so you get a good seal. If you have a mustache, use sun block or Vaseline on your mustache to help establish a seal.Lastly check for damage, cracks in the frame due to damage will leak. 

Here are some tips:

1. Pull your hair back to make sure it's not on your face,  or as for men, your beard may be blocking the perfect seal between the mask's silicone skirt and your skin, so you'll need to shave before putting on the mask.
2. The strap should sit high on the back of your head, not resting on your ears. If it rests on your ears it will get painful.
3. Do not over-tighten the mask strap.
