This is my second 11 ft coolaroo umbrella. I bought one last year and wanted one more to Mach this year for my other patio. I can not begin to tell you what a great umbrella this is. I have owned coolaroo products since the1990s.....you can not beat the coolaroo material. It will never fade, mildew or rot like other products. I was sick of buying umbrellas that cost as much and after one summer where all faded out in color. These umbrellas are huge and very sturdy. I have also owned patio awnings made by this company and after over 20 yrs of use the look as new as the day I bought them. Do not be fooled by the feel of he coolaroo material. It is different then any other. It is only made by coolaroo. Check out their web site for information but you will want to buy from Wayfair because you can not beat their price anywhere or fat shipping anywhere.....
