I am disappointed in cuben fiber as a fabric for gear. At first I really liked cuben and thought it would be a staple in my gear choices. Unfortunately every piece of gear has fallen appart. A simple pack liner made from 1 ounce weight cuben stretched until the fabric came apart. The liner was never used outside of my pack. The cheap wally-world stuff sacks were purchased at the same time and look brand new.
Sometimes you will never know the value of a moment until it becomes a memory.
