More freedom & safety in water

Key Feature
Visibility in open water

The swimming buoy provides you with better visibility in the water thanks to the yellow signal color. This makes it easy for other people, boats, and lifeguards to see you – an important safety aspect for any open water swimmer!

Key Feature
12.5kg of buoyancy when you need it

If you want to take a break while swimming – to rest, for instance, or if you get a cramp – you can also lay over the buoy to easily keep your head above the water. The buoy has a buoyancy of 125 N and is suitable for any body size.

Key Feature
Space for your personal items

You can store important things like a smartphone, keys, sunglasses, and even clothing and running shoes in the swimming buoy. A total of 12.5 l of volume is available in an area separated from the air chamber.


The READY interface can be used to add a cell phone pocket or an action cam to the inflatable buoy so you can operate your smartphone even while swimming. This means you can track your distance as you swim, for instance, share your location, or access important messages without having to interrupt your training. With the cam connector you can film yourself while swimming.

Key Feature
Predetermined breaking point

The swimming buoy is equipped with a predetermined breaking point so that the buoy separates from the belt at a load of 15 kg. This is an important safety feature, for instance if the dragline becomes stuck on a rock while swimming in a river.

Key Feature
PVC free and free from packaging

In contrast to most other swimming buoys, the swimming buoy by RESTUBE is manufactured to be PVC free. Only high-quality nylon TPU material is used in the construction. To eliminate the extraneous use of resources, we have also eliminated packaging and designed the swimming buoy so that it needs no additional outer packaging.

How the swim buoy by RESTUBE works


 Pack your personal items

Pack everything that should stay dry in the waterproof compartment, for example energy bars and other provisions, clothes and shoes, keys and sunglasses.


Fold the end 3x

Wrap the lower end of the buoy 3 times on the marking lines.


Close the buoy

Now close the floating buoy with the clip closure.


Inflate the buoy with your mouth

Inflate the buoy with your mouth and close the mouth valve with the cap.


Buckle the belt

Buckle the belt around your waist and place the buoy so that the pull line of the buoy is centered on your back. 


Enjoy more freedom & safety

Now enjoy your time in the water with more safety and freedom, knowing you have everything you need with you.

💡 Extra tip:

store your cell phone securely in the swimmingbuoy to share your location via GPS or track your activity


Unlike most other buoy manufacturers, we do not use PVC, a material that is problematic for nature and people, and use only high-quality NYLON / TPU in our products.

For the sake of the environment, we also do without elaborate product packaging. All important information is on a hangtag attached to the buoy.

The Restube floating buoy also has a predetermined breaking point that separates the buoy from the harness when the load exceeds 15 kg, which can be important in dangerous situations such as currents.

With the RESTUBE READY interface, the buoy can be supplemented with additional products. For example, a whistle or smartphone case (coming soon) can be attached to the READY patch.

No. If you need an approved life jacket, e.g. for stand-up paddling in Switzerland, you can use the pfd by RESTUBE.

The RESTUBE READY interface can be used to attach accessories such as a signal arrow or a waterproof smartphone case (coming soon).

Yes, the swim buoy by RESTUBE is designed to keep your personal items such as keys or smartphone dry. If you use the swim buoy on stretches where it could be damaged, for example by stones or rocks in the water, we recommend that you additionally pack all water-sensitive items in a waterproof bag.

einfach top

man spürt schon beim Aufblasen in der Hand die hochwertige Qualität, im Wasser dann beste Funktion, keine Beeinträchtigung beim Schwimmen, einfach nur top


Gibt beim Eisschwimmen Sicherheit.

Excellent Swim Buoy

Really good swim Buoy, you can even store things . Used for an open water meet and it was excellent. I really recommend it.

Irma VS
Great security and also practical

I gave this to my father who is an elderly swimmer by now. He likes it a lot for the security and the possibility to store and take wirh him valuable items while in water. Also my mother was very happy (since she started to worry a bit when he goes far into a lake). Then I bought one for myself, and since I am easily scared in deep water, it will give me so much freedom!

Restube Swim buoy

Ist ein nützliches Hilfsmittel beim Schwimmen. Einerseits kann ich Gegenstände sicher aufbewahren und vor Nässe schützen und andererseits kann ich sie beim Schwimmen mitnehmen.
