Inov8 Ultra Flask 0.5 with 10″ Tube


Out of stock

The versatile 500ml Ultraflask features a high flow phaser bite valve and a 10″ tube so it can be used with standard tops or straws depending on your preference. A large 42mm cap entry aids quick and easy refilling at race checkpoints. A durable, shaped RF welded construction and flexible TPU design ensures the bottle is soft and flexible, reducing any water movement and fitting to any body shape.

  • Specifications

    • Designed with a 42mm entry, it is easy to fill on the move, saving valuable time at race aid stations. The wide entry also means ice and drink mixes can be used on hotter days on the trails.
    • The two-in-one functionality of the Ultraflask means the tube can be removed and the high flow bite valve installed on the cap directly, adapting it to fit in either the upper or lower side pockets of the race vest. The tube can also be cut to the desired length and assembled with push fit hose connections.
    • Weighing just 48g, and constructed from soft, flexible and super-durable TPU, the bottle compresses as the fluids are consumed reducing any water movement. It folds away small and is easy to pack.
    • 100% BPA and PVC free. The Ultraflask is easy to clean and top rack dishwasher safe.
