anyone know about these or ever tested one?
a dude has just started selling them here and curious to know feedback as I've never heard of them!
Never tested one, but they are French, it is the brand started by Cyril Coste, a French kiteboarder (ex-Naish rider).
Cyril Coste has a kite shop in the north of France, so Lokahi is mostly known there, never saw one in the south, so I won't comment.
Note that Cyril has now also founded Takuma for all the foil-related gear, Takuma being more widely distributed, it may be better known than Lokahi nowadays.
