Go-To for Reef-Safe & Light-Weight Sunscreen
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Favorite sunblock to travel with. Appreciate the simplicity of it, and the fact that it rolls on and rubs in smooth. Of course the iconic scent is also a plus.

Great choice
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
After I suffered a second-degree burn from steam, I was told by my doctor that I would have to keep my new fresh skin sun-blocked for up to a year to avoid any scarring or hyper pigmentation. This has been a great selection as it is a roll-on, Which helps a lot with preventing messes that can happen with traditional sunblock bottles. I also like that it is easy to travel with, and the fact that it is zinc based.

My favorite new mineral sunscreen!
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
This is my favorite new mineral sunscreen! I've been searching for years for a product that is easy to apply, not messy, and doesn't show up too white. This roll-on is the perfect solution. I keep it near the front door and quickly roll the sunscreen on my hands, arms, and chest before leaving the house. The sunscreen applies so quickly and uniformly-- there are no bare spots or messy globs to rub in. Also, the roll-on keeps the sunscreen from oozing out of the tube and getting all over everything. Finally, the roll-on method also eliminates the frustration of having half-filled tubes and pumps where you can't even access the sunscreen when the tube gets low. Here's hoping this doesn't happen with the roll-on. Thank you Sun Bum for creating this wonderful product. I also love the reasonable price.

great product - it must be blended in well
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Love this stuff. The roll-on makes it easy to apply on the go. It leaves a white streak unless you blend it in. I don't mind the white streak - at least I know I applied the product.
