HydraPak Ultraflask Speed 500 ml

The HydraPak UltraFlask Speed 500 ml offers the perfect balance between lightweight design and stable performance. This soft flask is designed for runners and trail runners who want to hydrate quickly and efficiently, without the bottle moving or sloshing during their run.

The soft and flexible TPU material conforms to your running vest or backpack for a secure and stable fit. Thanks to its wider design and durable 3D-welded base, the flask stays securely in your pocket. As you drink, the flask shrinks, reducing water movement and increasing comfort.

The SpeedFill™ Cap opens easily for quick refills and seals leak-proof during transport. The wide 42mm opening makes adding ice cubes or sports drink powder easy. The high-flow bite valve automatically closes after each sip to prevent drips.

The UltraFlask Speed is compatible with 42mm water filters, including the HydraPak 42mm Filter Cap, and is made of abrasion-resistant TPU with RF-welded seams for added durability. It's also 100% BPA- and PVC-free and suitable for a wide temperature range—even freezing.
