The HydraFusion Tube uses a 6mm / 1/4in drinking tube and HydraPak Plug-N-Play connection. Check that your reservoir uses a compatible Plug-N-Play connection before replacing or upgrading the existing hose.
The 91.4cm / 36in length allows the tube to be routed from the reservoir compartment towards the shoulder strap area of a compatible running pack.
If insulation is not required, the HydraPak HydraFlex Tube provides the lighter standard drinking-tube alternative at 51g.
For freezing-temperature protection rather than hot-weather insulation, the HydraPak ArcticFusion Insulated Tube Kit is the cold-weather upgrade designed to help prevent ice from blocking water flow.
