Nataku, pardon my ignorance, but my Kelty bag is made of Cordura? The various Cordura messenger bags I've had over the years are a much stiffer weave. I realize there are various grades of Cordura, but I figured it wasn't used in these 70s bags, rather Nylon was the chosen fabric. Good to know that my bags are more water resistant than I originally knew! I have an external frame Gerry that hasn't gotten much use yet, but I hope to do some summer day trips in the mountains this year, maybe even a 14'er at my GF's request, heh. Edit: That Banana Equip. site is terrible. If they hired a decent photographer and web developer, they could get a spotlight on any number of tumblrs. Oh well, I'm sure the product is well made and worth the dough.
