concern is the durability of your product. I work in a high performance nylon fabrication
facility and I have not had the best luck with ripstop nylon. Why did you choose this
material instead of a higher performance product such as Kevlar or a course deiner nylon.
The covering we use is not nylon but a woven ripstop film which is very strong. It is a high grade version of the “blue tarps” you see.
I am very interested in the construction of your poles as well. Is the PVC tubing really
strong enough to last for three years?
