"In 2014 I started using the Restube buoy for training in long distance swimming and ice swimming. My Restube Active gives me safety and shows people on the shore and the boats nearby that I know what I am doing. I am safe and will be seen.

The handling - the inflating and packing - has improved more and more over the years. Especially in winter when hands are stiff, the Restube Active is the best safety buoy."

"I like to swim in cold and icy water. In these extreme situations, I want to be able to take a break every now and then to take a rest or simply to regulate my breathing. That's why my Restube always accompanies me on my way through the cold water."
