With the increase of UV rays in the environment, protecting your skin
becomes more important. A study was done at the University of Alberta,
Canada, to verify the effectiveness of different types of fabric in
filtering UV radiation. Of the 28 tested materials, 19 offered less
protection sun block with an SPF of 15. Polyester offered more protection
than cotton and darker fabrics offered much more protection than lighter
fabrics.
