The Coolibar Titamium Umbrella is the only one that makes sense in this area. I live in the Phoenix area and the temperature is usually well over 100 degrees in the summer. Even during spring the temperature can be in the 90's. When walking with this umbrella one gets the sensation of being under the cool shade of a tree. Absolutely no sun rays get through! Because I had one that I ordered years ago, I was able to convince several of my friends to get one also. Once they saw how nice the umbrella was, other friends wanted to get one of their own. I hope to try other of your products in the future. Thanks for a great product!
