Engineered for performance, the flask features a wide 42 mm opening for quick filling and easy mixing of hydration powders or nutrition blends. The high-flow silicone bite valve auto-seals after each sip, preventing leaks and delivering a steady flow exactly when you need it. Whether you're carrying plain water, electrolytes, or a custom energy mix, the Soft Flask 500 keeps hydration simple and efficient.

Built from tough yet flexible TPU with HDPE and silicone components, it's made to withstand tough sessions and long events. It’s completely BPA and PVC free, giving you a safe, reliable option for fuelling during training, races, or long adventures. The durable design ensures a long lifespan even under regular use, while the vibrant XMiles Blue colour adds a touch of style to your kit.

Ideal for runners, cyclists, and outdoor enthusiasts, this flask fits seamlessly into most hydration vests and belts. Easy to clean, refill, and reuse, it’s a must-have tool in any endurance athlete’s kit for maintaining consistent hydration without hassle.

The XMiles Soft Flask 500ml Ergo is designed to shrink as you drink, helping reduce fluid movement and bulk. The collapsible TPU body flattens down for a bounce-free carry, while the high-flow silicone bite valve offers quick hydration without the need to unscrew or squeeze. The wide neck makes it easy to fill with water, electrolytes, or energy drinks, and just as easy to clean after use.

Its BPA- and PVC-free construction ensures safe drinking, while the soft, ergonomic material adapts to any vest or belt setup for optimal comfort during extended activities. The auto-sealing valve and strong seams ensure leak-free use every time.
