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.

Yes, by replacing the CO2 cartridge, Restube is immediately ready for use again.

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 does not have USCG (U.S. Coast Guard) certification and does not comply with DIN standards. Why is this so? At first glance it seems strange that a product like Restube does not fit into the standard. On the other hand, it is clear that real great innovations are not yet captured in a standard. What few people know is that there are many products that also do not conform to a standard and yet provide a great benefit: E.g. rescue harnesses or rescue buoys for water rescue or for example avalanche backpacks until 2019. For avalanche backpacks, only after more than 25 years on the market, a separate standard was developed by the avalanche backpack companies together with the standard committees.

The basic requirement for a PPE (Personal Protective Equipment) is: the product provides protection from the hazard (in this case: protection from drowning) by putting it on alone. Restube was not developed for this purpose, but for very different application scenarios. Restube requires additional actions by the user, namely, the user must activate the cartridge's trigger and lean over the buoy. Restube, because it is not PPE by definition, cannot be approved as a life jacket.

However, Restube was never intended to be a life jacket, but rather to be used wherever more freedom and other forms of buoyancy are needed. The system meets the highest quality standards and enables completely new fields of application.

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.
