Sunbum: screen the sun!
Trust The Bum SPF 70 Original Sunscreen Lotion: my favorite sunscreen for Surf and Swim from trustthebum.com that lasts 80 minutes in water. I first discovered it at Hansen's, the surf shop at the beach town Encinitas in southern California. Just so you know, Hansen's sells a lot of really cool stuff for surf as well as casual beachwear! I am a big fan of their wetsuits and swim tees. :)
I found this sunscreen excellent for sun-protection–broad spectrum UVA/UVB protection, hypoallergenic, oil-free, vitamin E enriched, gluten free and approved by the Skin Cancer Foundation (the bottle has a seal of recommendation from the foundation), it's perfect for swimmers, surfers and anyone who stays out in the sun a lot. :) Check out shop.trustthebum.com for the perfect sunscreen for you. :)
P.S.: After shopping at Hansen's, you can head to the nearby Starbucks for the much needed coffee. :)
