I bought a tube of REI sunblock a couple weeks ago. I've talked to several guys who swear by this stuff. You put it on 20-30 minutes before going out in the sun and one of the big raves is that it doesn't run into your eyes when you sweat. Well, I've tried it a couple of times now when running and sweating - hasn't run into my eyes yet! It doesn't feel greasy at all. It just blends into your skin and then it's like it's not there. I've been using Neutrogena and have always liked it, but I think REI is the new winner.
