I rescued a 7-year-old boy who was completely overwhelmed and way too far out with his SUP. Would I have swum to him without my RESTUBE safety buoy? I don't think so!

Dennis

Something unforeseen can always happen in the water. So it's very reassuring to have a RESTUBE safety buoy with you!

Johanna Werner

When I was stung by a jellyfish in the open sea, I knew I needed help as soon as possible. I used the safety buoy to attract attention and luckily a fishing boat spotted me straight away.

Pia

I can swim well, but as I'm epileptic, it's important for me to have a solution in case of an emergency. That's why I always have the RESTUBE safety buoy with me in the water!

Experience matters – Athletes trust RESTUBE

Holger Lüning | Sports scientist and swimming coach

"There are just so many factors in open water that you can't possibly anticipate every possibility. One of the reasons I still feel safe is because of my constant companion, RESTUBE."

Kimo Kersting | Water sports enthusiast and professional Stand-Up Paddler

"It's incredible to be able to do the water sport you love without having to worry about what happens if I paddle too far or fall in. But also to be able to help other people in tricky situations. You too, wear a RESTUBE safety buoy, always!"

Nathalie Pohl | Extreme swimmer & Ocean's Seven finisher

“Despite the escort boat, you swim out there alone. RESTUBE Safety Buoy helps me keep my focus while swimming. The super small Safety System has no flow resistance and is weightless in the water. A pull on the trigger inflates the yellow Safety Buoy in seconds, which gives me an even better feeling.”

All FAQs

Who is ACTIVE for?

ACTIVE is versatile and suitable for a wide range of activities on and in the water - both training and competition.

Use ACTIVE for swimming, stand-up paddling, fishing, boating, triathlon, kayaking and canoeing.

What is the difference between the BEACH, ACTIVE and EXTREME Safety Buoy?

BEACH has a buoyancy of 50N and is ideal for families, children and seniors for leisure activities on and in the water. It is also suitable for stand up paddlers in swimwear in the summer - wherever there are no swimming aid regulations. ACTIVE has 75N buoyancy and is ideal for swimming or stand-up paddling, for training or competitions. EXTREME has a buoyancy of 75 N and is suitable for rough conditions when kite- and windsurfing, surfing or in professional use.

Can I use the RESTUBE Safety Buoy more than once?

Yes, after replacing the CO2 CARTRIDGE, the Safety Buoy is immediately ready for use again. The sales package contains the safety buoy incl. an original RESTUBE CO2 CARTRIDGE that must be screwed in before use. After use, the safety buoy is very easy to prepare for use again: Deflate, insert a new cartridge, fold the buoyancy chamber according to the printed instructions, and stow the whole thing in the pouch! ATTENTION: Only original RESTUBE CO2 CARTRIDGES are 1.) 100% quality tested, 2.) seawater resistant, 3.) level tested and 4.) the necessary release force is matched to the release. The cartridges comply with the standard for life jackets DIN EN ISO 12402-7. If other cartridges are used, it cannot be guaranteed that the safety buoy will fill without problems in an emergency and the trigger may be damaged.

Detailed instructions for how to get the Safety Buoy ready to go again are available in our blog: https://restube.com/blogs/news/how-to-pack-restube-care-and-maintain-correctly

How many times can a CO2 cartridge be used?

A CO2 cartridge can be used to trigger the Safety Buoy once. Afterwards, the empty CO2 cartridge must be removed, and a new original RESTUBE CO2 cartridge must be inserted.

This is simple, and only takes a few steps. You can view an instruction video here: https://restube.com/blogs/news/how-to-pack-restube-care-and-maintain-correctly

You can also blow up the Safety Buoy manually using the mouth valve. This is a practical option if you are using the Safety Buoy as a swim buoy, or for snorkeling.

You can purchase a 2-pack of original RESTUBE CO2 cartridges from our shop!
