The plain Chanel Pour Monsieur (*not* concentree) is a good masculine citrus. Think (current) Eau Sauvage or Eau d'Hadrien, but somewhat less zingy and more solid. the current version is less mossy than vintage, but is still ok. It is very difficult to find in the US, but is available in Europe or Canada.
However, do not confuse it with the pour monsieur concentree, which smells more synthetic, and I would rather buy other citruses - not necessarily the ones above, but perhaps Piguet Cravache.
