Polo Blue cologne by Ralph Lauren is a fresh and confident fragrance designed to add a little bit of warmth and zest to the modern man's day. The Polo Blue man lives for adventure and throws caution to the wind, and this long-lasting scent can go anywhere you do. Polo Blue men's cologne has top notes of melon, cucumber, and mandarin orange over an herbal heart of basil, sage, and geranium, all tied together and smoothed out by a base of suede, musk, and wood.
