Fishing shirts offer several levels of protection from the sun. Going from UPF 30 to 50+. You might think you may as well get the 50+ shirt, as at least you’re guaranteed protection. However, if you don’t need it and it costs more money than a UPF 40 or 30, then stick to what you need. You can also improve your sun protection by wearing undershirts or applying sunscreen if you’re out on the lake all day. Not all fishing environments require sun protective clothing, but it’s a good idea to get at least some items just in case.\r
