I like All Good Lips. REI had it last I looked, though it seems like they might be discontinuing it. No endocrine disruptors, no nano-particles, no reef-harming chemicals, comes in plain or scented and/or tinted. The only downside to the uncolored version is the same as any non-nano physical sunblock, they'll all have a whitish cast to them. Haven't tried the tinted kind.
