About Us

Shaping with more than 25 years of technical expertise, Patrik Diethelm is far more than just another name in windsurfing. From his humble beginnings as a shop customer himself to a high-profile F2 brand employee and PWA professional, his move to founding the brand PATRIK together with Karin Jaggi in 2010 was simply a natural progression. Today we create windsurfing boards and sails, rig components, foils and fins and some of the most advanced wings and boards in the industry. In windsurfing we find our roots. Windsurfing is still driving us. Winging, surf foiling and any other windsports are what we came to love more and more over the years.
