I'm rather late to the conversation, but from my experience, the Sunplay Sport SPF120 ones available at Watsons do the job exceedingly well (albeit it is falsely advertised as SPF120, which has been proven to be promotional jack).

I applied them for a use of around five hours in the hot sun (trip in P.D.) and I didn't receive a single burn, whereas a sibling of mine became red as a cherry without it.
