Why we carry it
Built by a scientist who surfs
SUNMUD started with a simple frustration: sunscreen that stings your eyes mid session, washes off after the first wipeout, and leaves chemical filters in the water. Co-founder and CEO Dr. Maricruz Carrillo put her PhD in Materials Science to work on a better formula, and when co-founder Miles Lee suggested adding clay, everything clicked.
The result is a non-nano zinc oxide and clay blend that sits on your skin as a physical shield, stays exactly where you put it, and dries to a clean matte finish. No oxybenzone, no octinoxate, no plastic packaging.
We met the SUNMUD crew at a San Diego event, tried a sample on the bay, and it has lived in our eFoil gear bags ever since. If you spend hours on the water, this is the stuff.
Stays put
Highly water resistant clay and zinc formula that won't run into your eyes. Tinted shades are rated for 80 minutes in the water.
Reef safe
Hawaii Act 104 compliant, with no oxybenzone or octinoxate. Mineral protection that is kind to the places we ride.
Plastic free
Recyclable aluminum and cork tins and compostable cardboard sticks. Fair trade and organic ingredients inside.
Gives back
A 1% for the Planet member and a local San Diego team that volunteers with Surfrider San Diego and Paddle for Peace.
Find your shade
Four tints matched to real skin tones, so you get full mineral coverage without the ghost white face.
Every shade comes as a 1 oz Sport Stick for quick, hands free application, or as a 0.5 oz travel tin and 1.5 oz tin.
Made for salt, sun and long sessions
After the session
- Solar Repair Serum: a lightweight organic after sun oil that rehydrates sun and salt stressed skin and gently takes off your mineral sunscreen.
- Muscle Salve: arnica, camphor, cajuput and menthol for sore legs and shoulders after a long day of foiling.
- Lip Balm: an unscented coconut based balm that keeps lips soft through sun, wind and saltwater.
