How to wash a hydration pack (not resevoir)? What's the best way to wash the pack part of a hydration pack (not the resevoir/hose)? Is it just like a back pack: cold water and a little detergent with air/tumble dry low?
Here's what I found from Dakine (brand I have), guess I should've trusted Google first!


  DAKINE Pack Washing Instructions
  
  We recommend washing your DAKINE backpack by hand in cold water with a mild detergent and soft bristled
  brush. If hand washing is not going to do the trick, the second option
  is to use a "front loader" washing machine. This is better because it
  has no center post for straps to catch on. There is still a chance the
  straps could catch so place your pack inside a pillowcase or mesh bag
  before washing. Wash your pack in cold water with a mild detergent on
  gentle cycle, Do not bleach your pack. Hang to dry in a warm but shady
  place, the sun could change the color of your pack. Switching the pack
  from inside out to right side out throughout the drying process is the
  best way prevent mildew. Damage caused by washing packs or bags will
  not be covered by warranty.
