DS is going on a really cool trip to California for an Oceanography class. He will be there Monday-Friday and there will be kayaking and snorkeling, etc. He needs reef safe sunscreen. I have never paid attention to this because we are really far from any oceans! The sunscreen HAS to be easy to use. I honestly don't care about good/bad on the chemicals list. I truly do not see him using some zinc cream he has to apply every hour. He is very fair and needs sunscreen that is easy to use so that he uses it. If it's spray on, that would be great. I need to be able to get it online--Amazon or something. (I doubt our local grocery store would carry it unless it is come really common brand like Banana Boat or Coppertone)

Thank you so much for any recommendations you have!!!!
