When you need a boost for yourself or others, pull the trigger. The sealed CO2 cartridge is pierced and fills the buoy in seconds. If you lean over the Restube buoy, it will lift your head out of the water. You can also wave the buoy to attract attention.

The most effective way to immediately contain critical situations in the water is to have additional buoyancy right next to you. Restube is so small that you can always have it with you and it doesn’t affect your mobility in the water. But if you want buoyancy, all you need to do is pull the trigger. You can also pass the buoy on to someone else or wave it to draw attention to yourself.

Yes, after replacing the CO2 cartridge, Restube is immediately ready for use again. After use, Restube is very easy to get ready to go again: Deflate, insert a new CO2 cartridge, fold the buoyancy chamber according to the printed instructions, and stow the whole thing in the bag! 

The idea of Restube came to founder Christopher Fuhrhop after a difficult situation in the water. From the University of Karlsruhe (KIT) he developed the idea up to the prototype and piece by piece his own production was set up in cooperation with experienced production partners in Karlsruhe. Function and the highest quality are priority factors without losing sight of sustainability.

If you lean over the buoy, Restube lifts your airways – in other words, your head up to your mouth opening – out of the water. The part from the head to the mouth is about the same weight for most people. That means it is independent of the height or weight of the user. For more comfort through more buoyancy, Restube active or extreme is recommended.

Restube is recommended for good swimmers aged 10 and over. The child needs to understand that in an emergency situation they need to trigger and hold on to the buoy. It’s best to let your child try Restube a few times in shallow water while you’re with them. They experience how easy it is to trigger and how well the buoyancy can help immediately.
