    What is a swimming safety buoy?

    A swimming safety buoy is carried when swimming in open water. The buoy increases your safety – and that of the other swimmers – tremendously. At RESTUBE, we specialize in water safety products. The Restube buoy – there are several variants for private use, as well as models for professional rescue – is a safety buoy stowed in a pouch that is attached to a strap worn around your waist. If you are in open water and pull the trigger, a screw-in CO2 cartridge inflates the buoy in seconds. The buoy provides you with extra buoyancy so you can rest and regain strength. You can also draw attention to yourself with the buoy by waving it or passing it to another person. Additional buoyancy in the water often immediately defuses a risky situation. A swimming safety buoy can be the most important accessory in open water swimming, just like a helmet is in cycling.

    When should a swimming safety buoy be used?

    A safety buoy should always be with you while swimming in open water. It is a very essential accessory for your safety during open water swimming. Restube is a buoy stowed in a pouch that is inflated only when needed by pulling the trigger and activating the CO2 cartridge. You can use the swimming buoy by RESTUBE if you want permanent visibility while swimming in open water, either for boat traffic or for other swimmers. It can be inflated via a mouth valve and – just like Restube – is attached to a strap and worn around the waist. It also provides you with an integrated waterproof compartment to store the essentials. For your safety and the safety of everyone else in the water: carry a safety buoy when open water swimming! You wear a helmet when you ride a bike, don’t you?

    What are the advantages of a swimming safety buoy?

    Swimming safety buoys greatly increase the safety of swimmers in open water. This is because they provide you with extra buoyancy whenever you need it. You can also hand over the buoy to a person in need. Additional buoyancy in open water can often resolve an unsafe situation immediately. A swimming buoy also gives you visibility. This way you will be seen by other swimmers or boats. Lifeguards and emergency services will also be able to spot you more easily. You can choose safety buoys that you inflate only when needed, like Restube. A screw-in CO2 cartridge inflates the buoy after you pull the trigger. Restube is small and convenient in a pouch attached to the strap around your waist. With Restube, you can still enjoy full freedom of movement.

    How is a swimming safety buoy attached?

    The RESTUBE safety buoys are attached to a strap around the waist. This means they have no measurable resistance in the water and provide you with full freedom of movement. You won't notice the compact system stowed in a pouch on your strap during your activity, but it will give you peace of mind knowing that extra buoyancy is just a pull of the trigger away. There are other methods of attaching swimming safety buoys, such as to your arm. But in our opinion, these have many disadvantages and limit you while swimming. For this reason, all Restube models for private use have a strap to make the open water accessories as comfortable as possible for you.

    What color is a swimming safety buoy?

    Swimming safety buoys are available in different colors, usually yellow or orange, sometimes red. This enables the buoy to provide a good contrast with the water, ensuring good visibility. Buoys from RESTUBE are yellow and are easy to see. Reflective strips can be added for swimming at dusk or at night. RESTUBE buoys are perfect for your safety when swimming in open water or triathlons.

    How is a swimming safety buoy tested?

    Safety buoys must pass an entire series of tests. The most important is certainly the practical test. Here at Restube, we work with several water sports enthusiasts who use our products during their activities and provide us with valuable feedback afterwards. In this way, we can ensure that our safety buoys optimally meet the requirements of the respective target group. 

    What is the best way to store a swimming safety buoy?

    It is important for you to store your swimming buoy carefully so that you can have fun with it for a really long time. Restube is designed to last a very long time and can be triggered up to 100 times depending on the model. So what needs to be considered? After using your Restube, hang it out to dry, separating the buoy and the pouch. If you have used it before in salt or chlorinated water, rinse it with clean water so that there is no residue. As soon as all the components are dry, put the buoy back in the pouch according to the instructions and store it in a dry place until its next use. You can also find detailed information about the care and maintenance of your Restube on our blog.
