Lots of skin cancer in my family. I am VERY fair skinned and have sun sensitivity issues for skin and eyes. My work is outdoors for 3 to 4 hours daily. Sun Sleeves are a blessing. They keep me from getting sun burned and, bless them, actually aid in cooling. They are also a tattoo cover which is a requirement for one of my jobs. Easy wash. Reliable, affordable, does the job. What more could I want? Well, maybe win the lottery!!
