Stay hydrated without the bulk or bouncing of a traditional bottle. The Precision Fuel & Hydration 500ml Soft Flask weighs just 29g and gradually shrinks as you drink, helping reduce liquid movement and sloshing while running, hiking or training.

The fast-flow bite valve provides quick access to your drink and is designed to feel comfortable on your teeth. Clear measurement markings make it easy to prepare your preferred hydration or carbohydrate mix, while the flexible flask can be compressed down when empty for convenient storage.

Made from BPA- and PVC-free TPU, the flask is designed not to affect the taste of your drink. Its lightweight and versatile design makes it ideal for running vests, hydration packs, long training sessions, races and outdoor adventures.
