I have been wearing these SPF50 shirts for a while now. Do they lose effectiveness over time?
I wonder if these long sleeve shirts are still effectiveness after a couple years of washes and wearing. Does anyone have any information about how long I can wear these and keep safe?
Excellent question actually. I wear my UPF jacket every day and wash it once a week. You’ve got me wondering now. 
good question! I've been debating getting SPF clothing. . .that is something to investigate before I invest. Thanks for asking! If you find anything you like, let me know. I am interested in your opinion. Scott skincancer.net moderator
