We developed our Signature line for the days that we live for. Our premium, mineral based sunscreen is specifically designed to offer the very best broad spectrum protection to those who work and play hard in the sun. It will never bleed into your eyes, never make your hands slippery, and won't come off during the most rigorous activities in the water, wind, or blazing hot sun. Sun Bum Signature is used and trusted by many lifeguard and beach rescue organizations throughout the U.S., including the Hawaiian Water Patrol, the North Shore Lifeguard Association, and the Eastern Surfing Association.
