This umbrella was a disappointment.  Though it stated in the description that it filters 50% of the sun rays out, it simply does not, compared to other umbrellas I have own that actually due.   The fabric is very thin with little texture.  Note also that this umbrella does not come with a tie of any kind!  I have to use two strips of an empty dry cat food bag to tie it down when it is collapsed, which works, but defeats the purpose of the umbrella adding a positive appearance to my patio.
