SATISFY® 500ml soft flasks designed in collaboration with HydraPak® to keep you hydrated during your runs.

• Made from ultra-durable, abrasion-resistant TPU, BPA and PVC free.
• Each individual flask can hold up to 500ml of liquid when filled.
• Flexible and easy to squeeze, the flask compresses as you drink, reducing water movement.
• The standard opening makes it easy to fill the soft flask.
•  The high-flow, self-sealing bite valve closes automatically after each sip, eliminating annoying leaks.
