The opinion of Aventure Nordique
The HydraPak UltraFlask IT is a flexible bottle with innovative IsoBound insulation technology that keeps water cold. This keeps water at an ideal temperature for 38% longer than a conventional water bottle.
It has a four-layer design, which makes it heatproof, robust and gives a better grip.
The ultraFlask IT has two caps: one with a bite valve cap and one with a 10 cm tube with a bite valve cap. The bite valve seals itself automatically after a sip, preventing any annoying drips. Finally, the bottle is flexible and fits into waistcoats, belts and water bag pockets for hydration.
The large 42mm opening makes it easy to fill the UltraFlask IT with ice and drink mixes.
