The Precision Fuel & Hydration 500ml Soft Flask is a lightweight, collapsible hydration flask designed for runners, trail runners, swimrun athletes and endurance training. Built to carry fluid comfortably without the bulk of a rigid bottle, it is ideal for long runs, race days, hydration vests, belts and “bring your own cup” events where compact, easy-access hydration matters.

Designed for practical performance, the PF&H 500ml Soft Flask weighs just 29g and uses a fast-flow bite valve that is easy on your teeth while helping you drink quickly on the move. The soft TPU body shrinks as you drink, helping reduce liquid movement and prevent distracting sloshing during running or fast-paced activity. Fill marks on the side also make it easier to mix Precision Fuel & Hydration drink mixes accurately to your needs.

Made from BPA/PVC-free TPU, the flask is designed not to taint taste and can be compressed down for easy storage when empty. With a 500ml capacity, screw-in bite valve lid and compact empty dimensions of approximately 21cm tall x 9cm wide, the Precision Fuel & Hydration Soft Flask is a practical hydration accessory for athletes who want a lighter, more portable way to carry fluids during training, racing and outdoor adventures.
