Review on NAVISKIN Men'S Lightweight Long Sleeve Shirts: Quick Dry, UPF 50+, Rash Guard, Swim & Hiking Shirts by Dan Weeman

These are very comfortable outdoor wear and the fabric is so smooth it feels like silk against the skin. I use these for mountain bike riding and also wore them while snorkeling and beach walking in Hawaii. The sizing runs a bit large in my opinion. I am 5'9' and weigh 160 pounds and the Medium is slightly too big, especially around the mid-section. The Small fits perfectly and looks much better for every day wear.
