Geigerrig 3L 100oz Hydration Engine

The 3L Hydration Engine works with most hydration backpacks. Where standard hydration packs allowed for the use by only one person, the Geigerrig hydration engine transforms the way portable water can be shared, sprayed, cleaned, and carried. The 3L hydration system is dishwasher safe.

  • Length:  16" 
  • Width:     7"

  • Wide Mouth: The Engine has a large, wide-mouth opening for easy refill with water and ice. It also provide convenience for maintenance, cleaning and drying. Reversible and dishwasher safe (top shelf).

The quick release valves allow you to easily disconnect the tubes and leave them positioned in the hydration pack while you remove the reservoir for filling and cleaning.
