I advise against a ready-made BOB. If you're in a situation where you really need the BOB then the gear it contains must be well-matched to you, your training, your experience & your locale. This is not a dig on the companies that make the premade BOBs but there is simply no way that they can make choices about what goes into the BOB and have those choices jive with what each user really needs.

BOBs, like FAKs, are just too individual to be mass marketed IMO.
