I'm pretty sure this isn't news to most, but for the sake of fellow newbs out there, I thought I would post this info on these clip-on magnets made for hydration pack tubes. They are pretty cheap and very handy.
I discovered the concept when I purchased an Osprey pack with a built-in magnetic clip on the hydration tube. When I switched to a Camelbak Antidote bladder (in an Osprey pack) I wanted to find something so I could take advantage of this great idea. The magnets on these seem to work even better than the Osprey's "built-in" ones, since you have more options in positioning them.
