Thanks for the review, Knot. I'll have to go try some out for my grand canyon trip. I see they sell it at REI.

I've got really sensitive skin and any sunscreen in the past has irritated it.. so come summer I go into hiding or I wear my new friend, my REI spf long sleeve. THis was a life saver when I was in San Diego last year. Saved my arms but my legs weren't so happy...
