What Restube does

Restube GmbH, founded in 2014 and headquartered in Pfinztal-Berghausen, Germany, designs and sells compact, CO2-triggered inflatable water-safety products, with the company name itself a portmanteau of "rest" (rescue + safety) and "tube." The core technology is a pull-trigger CO2 cartridge mechanism that inflates a wearable buoy in seconds, paired with a proprietary RESTUBE READY interface for accessories such as LED lights, whistles, reflectors, and camera connectors. The product portfolio spans 50N and 75N safety buoys (BEACH/ONE, ACTIVE, EXTREME, KIDS, PFD), swim buoys with integrated drybag storage, CE-certified ISO 12402 life jackets (SAIL, BOAT), a dog life jacket, PVC-free waterproof drybags, outdoor backpacks, and a Float Crew sub-brand of children's water-play products.

The company operates a direct-to-consumer e-commerce model at restube.com with localized storefronts for the US, Australia, and Japan, supplemented by a B2B Safety Partner program serving professional rescue, law enforcement, and humanitarian organizations (including NYPD, ADAC Luftrettung, DRF, DLRG, Sea-Watch, and the German Federal Police Aviation Unit) and an affiliate partner program. Revenue is generated predominantly through one-time hardware sales priced between roughly €15 and €229, with a recurring consumable stream from replacement CO2 cartridges priced from €11.99. Distribution and marketing span content, SEO, ambassador endorsements (athletes such as Nathalie Pohl and Josef Köberl), and flagship partnerships with World Triathlon, USA Triathlon, and Red Bull. Restube is privately held, has no disclosed institutional funding, and manufactures in Vietnam under stated German quality standards.
