Protection with days of white residue
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Mineral sunscreens have yet to master blending in and this is no different. If you're thinking of hitting the beach with your sexy bum protected it'd better be a ghost beach because you'll look like you've been dipped in white paint. Oh, and it doesn't wash off, so be prepared to look like Casper for days to come. It rolls on fine if you shake it well first and it does protect.

Great saddle bag item
Style: Face Stick, Size: 0.45 Ounce (Pack of 1)
I love the size! This small sized product is handy for the outdoorsman. Very convenient to keep in pocket or saddle bag. Product kept my ears, face and back of neck from sun burning. Easy to apply and rub in and was actually not oily feeling like most others. And an added bonus it help to keep nats and mosquitoes away from face, ears and neck!
