Ultimate Direction 1.5 Litre Reservoir

• 1.5 litre capacity: Compact reservoir capacity that keeps the water load relatively slim inside a compatible running pack.
• Wide Slide-Seal opening: Opens widely for filling and provides access for cleaning.
• Reversible construction: Turns inside out for thorough cleaning and drying.
• Plug-N-Play quick disconnect: Separates the reservoir from the drinking tube, allowing the hose to remain routed through the pack during removal and refilling.
• High-flow bite valve: Self-sealing valve provides good water flow and helps prevent dripping after drinking.
• Flexible TPU drinking tube: 92cm / 36in tube is PVC-free and designed to drape over the shoulder while resisting kinking.
• BPA and PVC free: Reservoir and drinking system are made without BPA or PVC.
• Beyond Lifetime Guarantee: Covered by HydraPak's guarantee against manufacturing and material defects.

Check that your running vest or pack is designed to accept a 1.5 litre reservoir and has suitable internal reservoir storage and a hanger or attachment point.

The relatively narrow 153mm width keeps the reservoir compact within the rear of the pack. Route the 92cm drinking tube using the pack's shoulder-strap loops or other hose-retention points so that the bite valve remains easy to reach while running.
