Xeryus Rouge by Givenchy Cologne. Xeryus Rouge is a masculine men's fragrance by Givenchy, created in 1995. Named after Xeryus, the Greek god, this manly scent combines the bold notes of kumquat, intense cactus, spicy tarragon, cedar needles and bold red pimento. This sensual fragrance has potent oriental undertones that stay true to its unique smell, despite changes in your stress level or excessive sweating. Xeryus is just as appropriate for office and evening wear as it is for running errands over the weekend.
