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

Constructed from ultra-durable, abrasion resistant, BPA and PVC free TPU.

Each individual flask can hold up to 500 ml / 17 oz of liquid when filled.

Flexible and easy to squeeze, the flask compresses as you drink, reducing water movement.

Large standard opening lets you fill the soft flask easily with ice and drink mixes.

Leakproof high-flow bite valve auto-seals after each sip, eliminating annoying drips.
