Question for you ladies. I have a neo in khaki that I bought in February and I love it but I've noticed that the fabric gets "stained" when water hits it. I have CKD so I'm always with a bottle of water and sometimes they "sweat" and my bag gets a water mark which remains and doesn't wash off like in the regular nylon. Have you had that happen? How do you deal with it? I've noticed also when there is rain drizzle. Thanks a bunch!
