Great for being on the boat! During the summer we are out on the boat in the bay, in the water, sometimes from sun up to sun down. This stuff works great for all over sun protection. Easy to spray on even with wet hands. I put it on my fiance's bald head and rub it into the tips of his ears too. It goes on nice and cool without any stinging. No lotion to sweat off and run into your eyes or break out your face either! We love this and always have it on the boat with us.
