The TUSA Sport IMPREX 3-D Mask and Snorkel Combo combines the UM-33 mask with a Hyperdry Elite dry-top snorkel. Choose it for the mask’s panoramic side-window layout and the snorkel features described below.
What is included?
- UM-33 mask.
- USP-250 snorkel.
Fins and a carry bag are not included with this mask-and-snorkel combo unless separately selected or purchased.
Features and benefits
- Mask layout: Three windows: front lens and two side windows.
- Silicone skirt and strap: flexible facial contact with adjustable strap tension.
- Model details: Hyperdry nose-purge valve assists mask clearing; it does not correct a poor seal or guarantee a seal around facial hair.
- Float-operated dry top: helps limit water entry when briefly submerged. It cannot provide air underwater and does not guarantee a dry mouthpiece.
- Silicone flex neck and mouthpiece: help you position the snorkel without pulling at your jaw.
- Drain chamber and lower purge: assist clearing water that enters the tube.

Mask and mouthpiece fit
Use the fit profile as a starting guide only. Face width, nose shape and cheek contours matter more than age or gender. Keep hair clear of the skirt, check that the frame does not press against your face and adjust the strap with light tension. The snorkel mouthpiece should sit comfortably without strong clenching.
For a gift, check the wearer’s current mask fit and allow time for a fitting before the trip. Our Hallam team can help compare mask shapes and mouthpiece comfort.
Surface snorkelling and care
A snorkel only supplies air while its opening is above the water. Practise fitting, breathing and water clearing in calm, shallow water before heading out. Rinse all equipment in fresh water after use and let it dry in the shade. Check the mouthpiece, straps and valves before your next swim. Follow the mask’s lens-care instructions and avoid abrasive cleaners, toothpaste and flame treatments.
