I used my new Toko water belt today for the first time. I must admit that there was some seperation anxiety when I left my old water bottle belt behind. I mean, I've been using the same bottle holder since middle school. Almost, I guess I stole my brother's at some point, but it was exactly the same, just unused. And I don't think he knows I took his, so don't tell him. Luckily I think he is too busy studying to read this. So there's going to be some adjustments to use this one. This water carrier is good because: it holds more water, it keeps hot drinks warmer for longer, you don't have to worry about the mouthpiece freezing shut, there's two zippered compartments for food/map/wax/cork, and it's yellow. It's drawbacks are that you basically have to stop and take it off when you want a drink and it sits differently on my back. I think that once I get used to how it feels, I will like it more than a bottle carrier.
