hey man, eau d orange verte is nice but seriously has NO longetivity, not just on me but alot of people. i would maybe go for chanel allure sport or edition blanche if he likes his citrus. your dad wouldn't probably want an 'old man' smell so sticking with chanel, allure is very nice. or if he wants to start his fragance journey with a bang, try chanel antaneus, strong potent stuff aimed at real men. also dolce and gabbana pour homme is pretty nice aswell, so try them out. hope i helped.
