in that the concept of snow-capped mountains is an invigorating, fresh experience, yes, Himalaya is fresh and it fits. as does Silver Mountain Water.
how in the world does Himalaya remind you of a dirty beach? because it has ambergris (whale-vomit) in it? haha... ambergris is used in TONS of fragrance... ones that are fresh, and ones that are not. don't draw any conclusions there.
