Coppertone Sport Sunscreen Lotion SPF 100+ Helps prevent sunburn. Higher SPF gives more sunburn protection. Retains SPF after 80 minutes of activity in the water or sweating. This high performance, ultra sweatproof, no-slip grip sunscreen bonds to your skin so it won't run into your eyes and sting. Extreme conditions that trigger sweating (heat, humidity, vigorous exercise) can make skin more vulnerable to UV damage. Added antioxidants help replenish skin's natural defenses. Broad spectrum UVA/UVB protection.
