HydraPak UltraFlask Speed 600 ml Soft Flask

HydraPak UltraFlask Speed 600 ml Soft Flask

The HydraPak UltraFlask Speed 600 ml Soft Flask is the largest of the Speed range, built for runners who want more water without giving up the low weight of a soft flask. At 46 g (1.6 oz) it still fits most vest pockets, carrying you further between refills on a long day out.

Features and Benefits

The SpeedFill cap flips open for a fast top-up at an aid station and closes with a leak-proof seal, so a refill costs you seconds rather than a stop.

Its soft TPU body shrinks as you drink, keeping water movement down even at 600 ml. Plus, the wider flange spreads the extra volume across a broader vest pocket, so the larger capacity does not fight your stride.

Product-Specific Use Cases

Carry it on longer trail sessions through Hatta or the Al Qudra gravel loops, where the extra 100 ml matters once the sun is up. In the Hajar Mountains, the 42 mm filter cap compatibility means the same flask covers a stocked aid station and an unplanned refill at a wadi spring.
