RESTUBE GmbH designs, produces and operates safety systems that are specifically designed for all kinds of aquatic sports. The water rescue tools from RESTUBE work with an inflatable floating unit – RESTUBE can be referred to as the inflatable backup for water sports enthusiasts. When in a critical situation, the floating unit is inflated using a gas cartridge and the user is thus saved from drowning. We interviewed the team on the idea behind RESTUBE, its founding period, and future prospects.
