I wouldn't take my set up, as is, offroad as in on trails. It has too much side-to-side sway unless you are riding very quietly. I think it'd be ok on fire roads if not loaded to capacity. I have a _big_ Camelbak that I've taken offroad, but it's not a current model, and I can't think of what it's called. I'll look when I get home.

http://home.alltel.net/nlevake/Dillbird/dill8.htm If you look at the bottom of the page, it's the blue pack that Dill is in. He's in a two quart Rubbermaid container, to give you an idea how big it is. He's actually in the helmet pouch. (Like, you rode your bike to school/work and carried your helmet in, in the Camelbak.) You can put a 100oz bladder in there, plus there is a whole huge compartment for clothes, plus mesh pockets on the sides, plus some smaller zipper pockets.

You could borrow it, Brandi, if you want. Or I think we have some BA military one we don't use. But big packs like that are quite warm, even though the part that rests on your back has some sort of support/channels for cooling.
