I use a UVA and UVB sunscreen protection from SkinCeuticals. A spf30 for daily stuff and a spf45 sweat proof for saturday ride training day and reapply it at least once during the ride.

One tip about sunscreen...MAKE SURE IT IS NOT EXPIRED!! If you have had it a while or from last year or last season...toss it and get new. Yup, I learned this the hard way. That's why I now spend a bit more on the good stuff with an expiration date well over a year. To me, it is totally worth it.

What ever you use just be sure it protects you from UVA and UVB rays. It should say on the tube.

Don't have any advice on the hat/visor situation though. Sorry.
