1- Material. Excellent. Tight woven very high quality fabric, yet supple and gentile and strong. 2 - Workmanship. Again, outstanding, nothing "shoddy" about assembly, all stitching straight and true. 3 - Effective and cool to operate in during local heat wave. 4 - Excellent value, can't say enough. Looking forward to many years of use, you have my full and heartfelt endorsement
