The Seeker by Hydrapak has been our personal go-to solution for frame bag storage for years. The rectangular and low bulk shape of the bladder is perfect frame bag hydration.
This bundled kit provides 2 Liters of water storage and fits perfectly into the top main compartment of our Tangle and Ripio frame bags. It also can be used along the down tube in the Ranger and Rifter bags.
The 2 L volume + hose and magnetic clip gives ample hydration capacity that exceedes double water bottle setups.
An in-line water filtration system can be configured using various plug and play options from MSR, Katadyn and others.
A significant savings over purchasing each item individually.
