Not sure if a bag is equipment?? Guess it is so I'll just go ahead with the daft question. 
Can anyone recommend a decent back pack, big enough for a DLSR body and couple of lenses, that also has enough space left over for being used as a day pack for mountain biking (ie hold cake, inner tubes, pump, cake, multitool)?
It'd need to be fairly well padded incase I land on it at any point, waterproof(ish) and ideally have a compartment for a camel pack bladder thingy.
I'd also like world peace and the moon on a stick whilst I'm here!
Any advice appricated!!!
