On holiday in Greece, it's 41 degrees and rising. I'm wearing my long sleeved rash vest in the pool. It's so easy, don't have to worry about how long I've been in the water for or re applying the sun cream all over my body. Its also great for keeping cool if you leave it on after a swim.
A few kids are wearing them but I'm the only adults. So many burnt shoulders here. Why aren't they a 'thing'?
