this is my (passion ;) field and so I get vey curious about the real meaning and translation of this 'evolutive'.
I reviewed dozen of sites dealing with sailing, boards, windsurf and kitesurf i.e. the products for which evolutive is used in French texts. I also checked bi/trilingual French sites hoping to find the English correspondent
BUT
1 - meaning - evolutive is used in an ambiguous way, compatible both with "evolved"/ high level & high performance item and with "evolving"/able to perform well in different situation;
2 - translation - ahahah this is the best part! In the English sections of the polylingual sites 'evolutive' just *disappears*. The item and its performance are described with no more mentioning of the 'evolutive' feature...
