Cordura is a durable synthetic fabric. I have had one strapped to one of my watches for over 2 years. It is very comfortable and the material, being fabric, is quick drying and breathable. As for its water resistance, this is what I put it thru once (strapped to a PAM183).
It went for a swim in the swimming pool followed by a soak in a hot spa. It spent about 40 minutes underwater in the swimming pool to a depth of 120 cm. The water temperature was about 28 degrees centigrade. It then went into the spa (20 minutes) where the water was 38 degrees Centigrade. It was taken out and was allowed to dry for about 10 minutes in 18 degree centigrade wind. This was followed by a 5 minute dip into running water at 28 degrees Centigrade.
It was then washed (in the bath) and allowed to dry in room where the temperature was 20 degrees Centigrade. It was subsequently exposed to rain and cold winds for about 1 hour and was finally allowed to rest. The result? As good as before the 'test'. Oh, the watch survived as well.
