Two valves keep water out
If a wave breaks over the snorkel, the upper valve sends most of the water out before it reaches the mouthpiece. Any water that gets past it drains through the lower valve.
Impulse Classic Flex
Two valves keep water out; the flex section drops away when not in use
Impulse Classic Flex belongs to Aqualung's Impulse snorkel line, which Aqualung introduced in 1989. Two valves keep water out. If a wave breaks over the snorkel, the upper valve sends most of the water out before it reaches the mouthpiece, and any water that gets past drains through the lower valve. Clearing the reservoir below the mouthpiece takes a gentle puff. The flex section is easy to position and drops away when you are not using it. Want the same two valves without the flex section? See Aqualung Impulse Classic.

Highlights
A gentle puff clears it
There is a reservoir below the mouthpiece, and clearing it takes just a gentle puff.
The flex section
The flex section above the mouthpiece is easy to position and drops away when you are not using it. This is the difference from Aqualung Impulse Classic, which has the same two valves but no flex section.
Who it is for
Great for
- Divers who want water kept out when a wave breaks over: the upper valve sends most of it out before the mouthpiece
- Divers who want easy clearing: a gentle puff clears the reservoir
- Divers who want the mouthpiece to drop away when not in use: that is what the flex section does
Maybe not for
- Divers who want a tube without a flex section: see Aqualung Impulse Classic, with the same two valves
- Divers who need the length, weight or bore size before buying: Aqualung's page gives none, so ask us on LINE before you order

FAQ
Impulse Classic Flex or Impulse Classic?
Both have the two valves that keep water out, and on both a gentle puff clears the reservoir below the mouthpiece. Impulse Classic Flex adds a flex section that is easy to position and drops away when not in use; Impulse Classic has none. Still unsure? Ask us on LINE.
How do the two valves work?
If a wave breaks over the snorkel, the upper valve sends most of the water out before it reaches the mouthpiece. Any water that gets past it drains through the lower valve.
Is it OK for beginners?
Aqualung does not rate this snorkel by experience level. It says a gentle puff clears the reservoir. Not sure? Ask us on LINE.
How long and heavy is it?
Aqualung's page does not give the length, weight or bore size. Ask us on LINE.
Which colours are there?
Two. Aqualung lists them by code; we name them from the photos: Black (all black) and Blue (blue tube, with a clear flex section and clear mouthpiece in the photo).
