Cleaning a CamelBak?

is it best to have the tube coming over one shoulder then having it resting on the opposite side.

That's totally up to the user... and the pack. Different packs have different tube routing. For me, bicycling or motorcycling, I prefer to route the drink tube under my arm and have the bite valve facing upward in the clip. For walking and hanging out, I route it over my shoulder. The hydration vest I use for running routes the tube over the shoulder and clips in at the waist. Some packs have the drink tube exit out of the bottom, in which case routing it under the arm is probably the most practical.

Try it both ways (or any other way you can think of!) and see what's comfortable.

It's still in the freezer, and I'm not worried about it. I do use it for kayaking, although not on my back. I can't remember the model. It's a few years old and it's the one smaller than the MULE. They have so many models, it's kindof ridiculous.

I agree Tulip. I don't know how old that link is, or if it's even "official." Disintegration of plastic vs. growth of mold is probably a wash!

PS. Did one night in freezer, one night in fridge and one night hung up with dryer. DH opened fridge and said, "There's a bladder in the fridge."
