How to choose the correct size of PRISM full-face mask?
If you have no way to try PRISM on before purchasing, you can use the following method to measure your face size: Close your mouth and measure the distance between the edge of your chin and your eyebrows (see picture). If the distance is smaller than 14cm, choose M size (women and youths). If the distance is greater – choose L/XL (men).
PRISM has been designed to allow users to admire the underwater world from the surface or from small depths. Its construction makes it ideal for those who consider conventional mask & snorkel set too uncomfortable or problematic to use. Available in two sizes, PRISM features a soft skirt and a adjustable silicone strap making it very easy to put on, take off and fit to most face sizes and shapes. PRISM also features a snorkel equipped with an Ultra-Dry top and an extremely efficient air circulation solution which not only makes breathing easy but also prevents fog from gathering inside the mask, guaranteeing clear vision. The user of PRISM is able to enjoy views of the underwater world in comfort unachievable for conventional mask and snorkel set.
Two sizes and two colours
PRISM full-face mask is available in two sizes, making it easier to fit the size and shape of the face of the user. Two different colour variations allow the users to choose the model that best matches their style.
Each PRISM mask is packed in a practical and durable pouch, which comes in handy for transportation and storage purposes.
PRISM full-face mask is intended to be used for snorkelling on or very near the surface of the water. When descending to larger depths, it is necessary to equalise the pressure in the ears, which is impossible in a full-face mask due to the lack of access to the nose.
Wide field of vision
Thanks to its construction, PRISM mask boasts minimal internal volume bringing the visor closer to the eyes of the user. This guarantees excellent viewing angles and an unobstructed field of vision in all directions.
Visor of the mask PRISM has been manufactured using a highest-quality durable polycarbonate.
Efficient air circulation system
PRISM features a snorkel with wide cross-section making air exchange easy. Cool, fresh air flowing inside the mask with every breath prevents fog from gathering on the visor.
Bottom purge valve
This valve serves a double purpose. Its secondary use is to aid in removing used air from the mask. Its primary use is to drain water from the mask in the event it found its way inside. You only need to lift your head above the water or exhale energetically and the unwanted water will be removed.
Adjustable strap made of highest-quality antiallergic silicone allows the user to easily fit the mask to your face and makes putting the mask on and taking it off easy and comfortable.
The skirt on the PRISM mask has been made using the highest-quality antiallergic silicone formed with LSR (Liquid Silicone Rubber) technology. Its shape and material properties allow it to comfortably fit many face sizes and shapes. Additionally, a double seal on the skirt makes it even more watertight.
A special float enclosed in a durable casing is responsible for preventing any water from getting into the snorkel. When the casing is submerged, the float moves towards the airhole and closes it, so that water access is blocked.
PRISM mask is characterised by its minimal internal volume. Additionally, it features unique strap regulation system that makes it possible to completely disconnect it from the frame. This, together with removable snorkel makes PRISM easier and safer to store and transport.
