I like having a tube for easy hydration, but I don't like not knowing how full my water bladder is buried in the pack. These tubes hook to your smart water bottle, or Nalgene which are stowed outside of the pack. Easy to see how much is left if you take a quick break.
With my pack and inflexibility, it is very hard to remove a bottle drink, and return it. Most times I have to take the pack off.
If you like something similar, please post a link.
Thanks for your comments.
