Review on Stay Protected Under The Sun: HOPESHINE Arm Cooling Sleeves With UPF 50+ UV Protection For Cycling And Outdoor Sports (3-Pairs) by Rick Malloy

These sleeves work great for protecting my arms as I work outside all day. They are comfortable and very flexible. It is a layer though so when it is hot outside it feels like your arms are wearing a long sleeve shirt but not as thick as that long sleeve shirt. I have not been sunburned while wearing them. I give 5 stars for comfort yet four stars for questioning if they are truly UV protection. There is nowhere on the product nor the packaging that states these are UV. My UV shirts have the UV logo on them yet these sleeves do not. The only place that states these sleeves are UV protection is on the seller page. I hope revain has quality assurance to ensure their products are truly what they say they are. Perhaps I need to do more research myself on this topic. As stated before they are very comfortable.
