When I think of clean scents, my mind jumps to:
Pleasures for Men by Estee Lauder
Eddie Bauer Pure
My favorite part about these scents is I don't detect any cheap Juniper Berry in them.
Clinique's Happy would probably fit the bill, although I'm not recommending it because I detect the aforementioned foul Juniper Berry smell. But if you like that, you may want to try it.
