It will fit into any water bottle cage though it will rattle. Keeps drinks hot (too hot really) all day. You can operate the top with one hand and lock it down if you have to toss it in your pack. Only problem is that is is pricey and hard to find. And it keeps liquids too hot so it's easy to scald yourself.
