Review on O'Neill Men's Basic Skins UPF 50+ Short Sleeve Rash Guard: Stay Protected and Stylish! by German Diaz

After 6 orders and 5 returns I found the one that fits me. I used it snorkeling in Hawaii and it worked great. Here is my understanding of the sizing issue: 1. They are very small; You should order two sizes larger than you are, and 2. the manufacturing process is inconsistent (i.e. poor quality control) so two shirts in the same stated size (s, m, l, etc.) can vary significantly in actual fit. .I'm 5'10 and 155 pounds and I'm a solid "medium" in shirts. I'm an active snorkeler and have worn rashguards for many years so I know when they're tight because rashguards need to fit snugly, not when they're too small. I ordered the mid length and short sleeve versions of the rash guard and they were so small I literally couldn't pull them over my shoulders. So I returned them and bought the same large rashguards. They were also too small and I had to send both shirts back. I ended up ordering extra large versions of these shirts and when I received them the short sleeve version was a proper slim fit (like rash guards should be) but the long sleeve version of the same size was actually too big. I left the short sleeve version and brought back the long sleeve version. So trying to order the right size for this rashguard is more a matter of luck, but I recommend starting 2 sizes larger than you normally wear.
