No White Cast, Fragrance Free
Love this Coppertone sunscreen. No white cast, fragrance free, and it stays put with water and sweat. SPF 60+ protection keeps me covered without reapplying constantly. It feels breathable on the skin and does not clog pores, so it is comfy for daily wear and workouts. Highly recommend.
