I think Ozone is a German company with kites made in Vietnam.
it´s definatly not German - i know that!
factory is in vietnam thats true...
However the originators of ozone are English I believe. So it makes sence that there's some euro connection.
some owners are english as far as i know - but england doesn´t use the euro!
we use the catalyst in our kiteschool for 2 years (besides other brands) and the ozone kites are the teachers favorites!
