I bought 2 of these to take to Cancun. They did exactly what I was expecting. I don't have any sort of sunburn, and we were out A LOT. They also seem to keep me much cooler than a regular short sleeved t-shirt, which I was concerned about, but pleasantly surprised. I will be recommending these to everyone!! It was nice to throw it back on after swimming and not worry about reapplying sunscreen all the time.
