I got this Coola SPF 45 Sport from a gift bag at a show I worked on. I had never heard of this brand before, but they are certified organic upon checking the website. Their sunscreens are not cheap - average price is $30. I use this SS on my face and I have to say, it's one of the lightest SS out there for it being organic. It's easy to blend, not very oily, and melts in to your skin w/o leaving a white cast. As far as lasting power, I can't say since I only wear it underneath my MU at work and haven't worked out or exercised in it. Works well underneath MU too.
Overall, a great SS with great protection - I like SS's above 40 since I have melasma. It hasn't aggravated my melasma either, which is great. Overall, a very good SS and best of all it's organic!
