Sundercover® was born from a simple idea between two friends—one married to a dermatologist, the other with a golf-loving dad who had been treated for pre-cancerous spots on his scalp. Concerned for their families and inspired to make a difference, they set out to create a smarter, more stylish way to stay safe in the sun. What started as a patent-pending UPF 50+ hat liner to fit inside your favorite hat has grown into a full line of thoughtfully designed sun-protective apparel and accessories.

Today, Sundercover® offers a complete collection of UPF 50 and UPF 50+ products—from hat liners and caps to hoodies, polos, rashguards, long sleeve shirts, and outdoor-ready essentials. Each piece is crafted using the most technologically advanced fabrics, combining superior UV protection with breathable comfort and trend-forward design.

Our mission is to help people enjoy the outdoors without compromise. Whether you’re hiking, golfing, swimming, or relaxing by the shore, our products are made to move with you—protecting your skin and keeping you looking and feeling your best. For us, it’s about bringing fashion, function, and peace of mind to a community that loves the sun—but loves sun protection even more.

Be Safe. Play Outdoors. Live Sundercovered.
