Surfmud is an Australian brand made by surfers, for surfers. It started with the original tinted zinc covering cream, and the range now includes Ocean Addicts, a rub-in mineral sunscreen, and Surfbaby, an SPF30 made for babies and anyone with sensitive skin, both available in tubes and tins. Zinc oxide does all the work, with no chemical UV filters and no nanoparticles, so it's reef safe, and it's water resistant for four hours. I don't stock the full range, as not everything meets my NO List.
