Really THE NICE and convenient snorkel, which might be spread at about half for storage/transportation. The softness of the silicone is pretty enough for comfort mount and breathe. The High-TEC feature: both upper and lower valves looking and sounding doubled. This is 'overkill' from my point of view, but newbies might get a lot of comfort waves with such advanced mechanics, while the 'old dudes' will not get more troubles with it. So, such model is a 'must have thing' in each No1 diving set. A lot of thanks to Designer, Manufacturer, Trader, Ali, and each Post Office on the way!
