Ventile's pure cotton, extra-long staple fibers, woven tightly. A lot of people prefer it to Gore-Tex, etc., but it doesn't seem to be quite as waterproof. The big adv. to me, is that it should get better with age, while Gore-Tex and other things don't. Was developed for the British military. There's different weights and this one is the heaviest.
