Adult Snorkelling and Sea Diving Frameless Mask Cressi F1 black

You need to position your mask on your face without the strap, and press with your hands to make sure it’s firmly in place, blocking your breath.If the mask "suctions” properly, and stays stuck to your face, it’s perfect and means that it is your size and will be watertight.If it unsticks and falls off, that means that air is getting through, and so water will get in, so you’ll need to try another size or another mask.

New mask: Wash your mask with washing-up liquid and warm water, using your fingers, to remove any grease. Do not use a sponge.Before each use, spit into your mask and wipe the lens with your fingers to rinse the mask.Dampen your face with the water to limit heat loss between the skin and the lens of your mask, as this will reduce mist.Use an anti-mist spray to completely eliminate mist.

Flexible part of mask in contact with face.

Silicone is an extremely flexible material. A silicone skirt conforms gently to the contours of the face, creating a watertight seal.

Tempered glass is two to five times more durable than traditional glass. If it shatters, it breaks into small pieces, reducing the risk of a major accident.

Micrometric buckles together with the notched strap on either side of the mask allow easy and highly accurate adjustment of the mask, even when wearing gloves.
