Best snorkel on the market!  It's well designed with a jaw-friendly mouthpiece design, an efficient downstream purge valve which can't fall out, and a superior mask strap attachment which is easy to use and difficult to break.  However its best feature is that 95% of it is flexible silicone, so you can roll it up in your pocket, squash it in your dive tub or suitcase, as generally mistreat it without fear of it breaking.  As snorkels go the Platina II may be on the expensive end of the scale, but it is money well spent, as you'll likely never need to replace it.

• Hyperdry system with three current rectifying plates
• High flow and angled purge valve to eliminate gurgling of water and allow bubbles to pass by the face when purged
• Ortho-consciously designed mouthpiece for ultimate comfort
• Silicone flexible neck
• Detachable two-section swivel adapter for free movement

COMFORT SWIVEL
The Comfort Swivel adapter makes it possible to slip the mask strap into the slit with no hassles. The two-part construction allows the snorkel to rotate and can be attached in a horizontal position.
 
HIGH FLOW PURGE
The High Flow Purge design used on TUSA snorkels offers a covered large diameter purge valve for simple, quick clearing, reducing the amount of water remaining in the mouthpiece in an instant. 
 
HYPERDRY SYSTEM
The Hyperdry System keeps the main pipe dry by ejecting water through an independent escape pipe. This unique design utilizes the angle of the snorkel pipe and the resilience of the water surface to eject water.
