The Maine state prison in Windham has Camo Gortex Material for sale. The material is 54" wide & as long as you want. Very rugged water proof & breathable. For every 3 running feet is 5$. Great stuff very light & tough. I have a 6x10 shack & I can load it alone. You will need to call the prison store & they will give you the name & number in the prison to call. The guy's name is Burt Jalbert
