The updated Platypus Drink Tube Kit offers two great options: 1) It replaces an old or damaged Hoser™ drink tube, and 2) It converts any Platypus bottle product with a threaded-opening into a handy hydration reservoir.
The kit comes with the threaded closure, a ¼" drink tube, a lapel clip, and the new fast-flowing HyFLO™ bite valve.
