About the snorkel:
Ergonomically designed mouthpiece and airtube
Anallergic silicone
Internal diameter of the tube is 20mm, a specific dimension to optimize the air flow rate
The strap holder is easy to use and reduced to minimal dimensions
The tube of the Zoom Pro is manufactured in TPU, an extremely flexible plastic material with a high mechanical strength used mainly for articles subjected to wear and for all heavy-duty engineering components
The tube will undergo no swelling in water and won’t yellow under the action of UV light
The snorkel has a high rebound elasticity and "snappiness", allowing the diver to fold it when it is not needed, and to take it out whenever the use of a snorkel becomes a necessity
Rigid enough not to vibrate during the ascent
Warranty:
12 Month manufacturer warranty
