HydraPak took their go-to flask and added filtration to create the HydraPak UltraFlask + Filter Cap. Use it to lighten your load and drink right from the source on long runs and hiking trips.
- The light and compact filter screws on top so you can drink right from the flask; or, if you're carrying more water, use the system to fill a bottle or reservoir
- Filter removes E. coli bacteria, cryptosporidium parvum cysts and giardia lamblia from approximately 1,500 liters of water at a rate of more than 1 liter per minute
- Effectively removes common waterborne bacteria, such as E. coli (99.999%), and parasitic cysts (99.9999%) per HSF 42
- A flexible and structured grip makes it easy to hold the flask while screwing and unscrewing the filter
- Soft material conforms to most hydration packs and larger vest pockets for a secure and stable fit
- High-flow, easy-drink bite valve auto-seals after each sip, eliminating annoying drips
- Large 42 mm opening lets you fill the flask easily at any water source
- Flask holds 0.5 liters of water
- Flexible design shrinks as you drink, minimizing water movement
- Included backflush adapter plugs into filter valve and threads onto a HydraPak Stow (not included) or bottle to backflush the filter with clean water to restore its flow rate
