I was very disappointed with this product. I love the SPF 85 from the same line so I thought I'd like this one as well. I was very wrong. The 85 goes on easily and is light and wearable. This 50 is heavy and never seems to sink in. I felt gross all day. It also smells stronger, which was very unexpected.
In short, thumbs down for the SPF 50 but try the 85.

I'm a really pale person (NW15) who also likes to go sailing in the summer. As you can imagine, I've been through truckloads of different sunscreens, and I love this one. It smells nice, doesn't leave you feeling too coated/slippery, and lasts in full sun with activity and sweat for about 3 hours. I also like the Sport version of this, I find it has better staying power but is more expensive and doesn't have the skin-loving ingredients this formula has. I also like the twist-lock cap- keeps this stuff from going off in your bag.

very practical and convenient, but i don't think it's as quick-drying as they claim it to be. still a nice sunscreen tho.
