Keeping you comfortable and protected all day long with a single application, Sawyer Stay-Put SPF 30 sunscreen uses a non-greasy Breathable Matrix Formula that spreads into all layers of your skin, uniquely penetrating where other sunblocks simply can't go. Free of Oxybenzone, Paraben, and Dimethicone, fragrance-free Stay-Put SPF 30 is enriched with aloe vera and vitamins to help your skin retain moisture. It's recommended for most uses, and a single application penetrates deep into your skin for all day sun protection. Sawyer Stay-Put sun block is also engineered to be effective when combined with Sawyer Insect Repellents. While most sunscreens hold their lotions in the top two layers of skin, Sawyer Stay-Put SPF 30 sunscreen uses a special technology to bond the sunray absorbing agents deeper into your skin, uniquely penetrating where other sunblocks simply can't reach. Sweat and water pass over the deeply absorbed compounds without flushing the protective sunscreen away. The Stay-Put formula was engineered to spread the same volume of lotion over a larger cubic area of skin, requiring less lotion per area of skin and producing a more comfortable, breathable feel — all while providing great all-day protection. You'll hardly even know you have sunscreen on. Since 1984, Sawyer has used technological advancements to create products that keep you outdoors — from the backcountry to the backyard — including insect repellents for both skin and clothing, water filters for camping and emergencies, and sun protection.
