@ManiusTerentiusPullus @Syoten @Setonix @Bug72 Prototypes 3 & 4, these are all rideable and work, you can drink on the move, both really secure, the bottle aint moving, easy to remove, use most types of bottles with a screw cap. The drinking tube attatches to your clothing with a rare earth magnet, so if you upd it just detaches. A few ideas for you, that are practical, cheap and work for drinking on the move, bottle about as secure as it can be.
- Fit any bottle hydration tube kit.
- Stretchy silcone bottle carrie with carabina.
- Netting bottle holder.
Simple cheap and they all work just fine. Only the tube to cut down to the right length. 
Muni friendley, jump, hop, upd, that bottle aint shifting 
both also take my pac up waterproofs for winter rain , storage plus waterbottle, sorted.
