The wife is starting to get more and more into biking. She is out pretty late on some roads in the country and I would rather have her a bit more safe then sorry if she has a flat and needs help.
The one that I am looking at is the camelback dream http://www.rei.com/product/733420 but I don't much about hydration packs. The big thing that concerns me is the the sweat the would come off of the bag from the water so it looks like stainless is the way to go. I am thinking a Smith 642 would work perfectly for this.
Anyone here have any experience with this stuff?
