I'll just wear light hoodies and sweat pants if I go fishing sometimes my face still gets burned a little because while I don't look at the sun much or get much sun directly to by face because of my hoodie, the sunlight is also reflected off the lake into my face and I often overlook that bit .... I've got a full beard so that blocks most burns now but I've had many really bad burns when I was young 10 to 16 years old . Now I'm 43 and I'm constantly D deficient even on 5000 units daily, if I don't supplement I really feel like crap and get sick more often.
