About Perfekta of Sweden

PERFEKTA på Tjejmilen PERFEKTA of Sweden

PERFEKTA of Sweden® was founded in 1986 by Gerry Rönnmark. I realized that there was no good way of running with water. That is why I invented the elastic fluid belt with the small plastic bottles.

Still today Gerry and Kristina Rönnmark own and run PERFEKTA of Sweden. For over 30 years they have made new models, bags and other accessories for runners. 

If you have any questions Kristina and Gerry will help you. You can email the at office@perfekta.nu.

The bridge run 2000

When the Öresunds bridge between Malmo and Copenhagen was built in 2000 it was celebrated by the Bridge run. PERFEKTA of Sweden developed and sold 92 000 special fluidbelts to that run, each runner got one. This was because it was problem to have fluid stations on the bridge.
We still see runners use the belt from the bridge run when they run today. That is proof of quality to us.
