More freedom & safety in water

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!

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.

Storage in the integrated dry bag

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.

Cool extras for individual needs

Add a waterproof, touchable smartphone case to your swim buoy pro. The case is attached directly to the buoy via the RESTUBE READY interface using the READY connector. You can use the same system to attach a mount for an action camera. You can also transform the Swim Buoy Pro into a backpack with the practical shoulder straps.

PVC free

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.

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. 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.


Enjoy more freedom & safety

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


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.

Both products are recommended if you require permanent visibility and additional buoyancy for emergencies in the water.

The swim buoy pro is the right choice if you need a dry bag to store various items. This also applies if you want to add a mobile phone case, action camera and shoulder straps.

The additional safety features, such as reflector strips, LED light and signaling whistle, can be retrofitted to both models.

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.

Ensure that there are no objects left in the dry compartment of the swimming buoy. Next, smooth it out towards the opening to remove all of the air from the dry compartment. Finally, begin rolling up the buoy while pressing the cap into the mouth valve to keep it open. Warning: If there is any residual air in the dry compartment, the swimming buoy will not be able to be rolled up completely. If this happens, repeat the smoothing process and roll up the buoy again.

Valuable safety tool

It fulfills it's purpose, has good quality, quick shipping Clipping a GoPro on it can lead the boy to turn around and the camera to be underwater. The safety of the device is not affected though. Recommended. Valuable for anyone who performes open water swimming

Hi George,

Thank you for leaving a review for our swim buoy by RESTUBE! We're glad to hear that it fulfilled its purpose and that you found the quality to be good. We apologize if your GoPro turned around and went underwater while using the buoy. Just a friendly tip, if you put a little bit of weight in the buoy, like a towel, it should prevent this from happening. We appreciate your recommendation and hope to continue providing valuable safety tools for open water swimmers like yourself.

Stay safe and happy swimming!

Great product, quick and kind customer stumer support

The swim buoy is prefect for swiming longer distances in free water while having all belonging with you. The water restistant smartphone case is a nice addition to improve safety. However, to connect the case and the buoy an additional connector is required. Make shure to add this to your shopping cart.

all the information you need

Learn about your Restube

Where can you find swimming buoys?

You can find a swimming buoy wherever water sports accessories and water sports safety equipment are sold. At RESTUBE, we specialize in water safety products. Our inflatable swimming buoy with integrated waterproof dry bag is perfect for open water swimming, such as triathlons. It is worn with a strap around your waist and provides visibility and extra buoyancy when you need it. The swimming buoy has almost no resistance in the water. Test it yourself on your next open water adventure!

How big is a swimming buoy?

The size and length of a swimming buoy can vary. The swimming buoy by RESTUBE is 76 cm long and has a volume of 12.5 liters. The buoyancy is specified in Newton and amounts to 125N – which corresponds to about 12.5 kg. This is sufficient for an adult leaning over the buoy. This keeps the head and airways above water. A swimming buoy with a length of 76 cm in the signal color yellow is also ideal for ensuring visibility while swimming in open water – for your safety!

What colors do swimming buoys come in?

Swimming buoys can be different colors, but usually they are yellow or orange to provide a contrast with the water for visibility. The swimming buoy by RESTUBE comes in a vibrant yellow to ensure just that. If water sports are also practiced at night, reflector strips can be added. The swimming buoy by RESTUBE is perfect for the safety of open water swimmers or triathletes. It also features a separate waterproof compartment, called a dry bag, where things like running shoes, keys or energy bars can be stowed.

What materials are used for swimming buoys?

Many swimming buoys are made of PVC. This is not the case with the inflatable swimming buoy by RESTUBE with integrated waterproof dry bag. It is 100% PVC free. Only high quality and durable nylon TPU material is used.

How are swimming buoys installed?

Many swimming buoys are attached to a strap that is worn around the waist. There are also models that you can wear on your arm or even with your backpack system. However, these variants have more disadvantages than advantages according to our tests. The swimming buoy by RESTUBE for your safety when swimming in open water comes with an adjustable waist strap and the rope length of the buoy can be adjusted individually.

Why are swimming buoys important?

Swimming buoys are very important to have for water sports in open water. Swimming buoys ensure visibility when swimming and participating in triathlons. This makes it easier for other water sports enthusiasts, passing boats, or lifeguards and emergency services to recognize you. Also, swimming buoys provide buoyancy whenever you need it. For example, if you want to take a break in the water, regain your strength, or need to get your bearings. Additional buoyancy increases your safety considerably and can often quickly defuse a critical situation. You can also separate the swimming buoy from you and pass the buoyancy to another person. The swimming buoy by RESTUBE also offers you a separate waterproof compartment, a dry bag where you can store useful things like running shoes, keys, and energy bars.

What kinds of shapes can swimming buoys have?

A swimming buoy floats behind the swimmer and is also often equipped with a waterproof dry bag for personal belongings. Inflatable swimming buoys come in different shapes and sizes. The swimming buoy by RESTUBE is “tube-shaped”. For this reason, the English word “tube” is part of the name RESTUBE. The inflatable swimming buoy by RESTUBE is 76 cm long and has a diameter of 35 cm. Its shape and size are perfect for open water swimming, such as triathlons. They significantly increase the safety of the wearer. There are also other forms of swimming buoys designed for specific applications.

How much do swimming buoys cost?

The prices of swimming buoys vary, as does the quality. Our swimming buoy by RESTUBE has been extensively tested and is made of high-quality, durable materials. The buoy is completely PVC free, as we only use high-quality nylon TPU material. Try our swimming buoy in open water swimming or in a triathlon and ensure increased safety for yourself, as well as others, with visibility and extra buoyancy when you need it. The inflatable swimming buoy by RESTUBE is available for 39.95 euros. Sign up for our newsletter now to make sure you don’t miss out on any of our special offers!
