Givenchy's Pi Extreme perfume for men was introduced in 2015. What is the scent of Pi Extreme? It's an aroma with a bouquet of aromatic woody, Smokey, and dry scented tones that will leave you feeling mysterious, natural, and sensuous. When you examine it more closely after it's been applied, you'll detect a lingering quality of gentler fragranced tart, balsamic, and resinous hints that conceal an essence of soft, welcoming, and soothing sentiments.
