I rarely do promotion of products here, but I saw a video of this on BikeCommuters, and was pretty stoked about it. Why you ask? Because I hate wearing something on my back while out on the trails; I have avoided a Camelbak just for that reason. This tote looks kind of burly for me (weightweenie?), yet I could see many people using this as a great trail riding or commuter pack in WV:
Edit: Think how great this would be on a bike camping jaunt??!!!
