I work on hot rooftops with a white surface, surrounded by metal duct work that reflects the sun all day long. It could be 70° at ground level but 100° on the roof. This is the best unscented, sweat proof sunscreen I have been able to find. I only need to reapply at around 1:00pm. I made it the entire summer without a sun burn. Pretty impressive.

Spray is so tough to

Size: 5 Fl Oz (Pack of 2), Style: SPF 70

The spray doesn’t work at all - they are so hard to press down that it’s impossible for me to do without using two hands - it defeats the point of a spray.
