I seem to like the caramel one for the '68 and black croco for the '65.
I'm still searching for one for mine, and most probably will go with a slightly padded cordovan or caramel oil tanned one.
By the way, has anybody seen the "vintage leather" one that will come with the MC Navy Seals? May be we are lucky and it matches the Polaris.
Saludos,
Tony
