Salomon Soft Flask 500ml / 17oz Ultra 42 – Lightweight Hydration for Trail & Ultra Running
The Salomon Soft Flask 500ml Ultra 42 is designed for runners who demand lightweight, efficient hydration on the move. Built to fit seamlessly into Salomon vests and most standard flask pockets, this soft, compressible bottle shrinks as you drink—reducing sloshing and maximising comfort during long runs and races.
With a high-flow bite valve, hydration is quick and effortless, helping you stay fuelled without breaking rhythm. The soft TPU construction is flexible, durable, and comfortable against the body, making it ideal for trail running, ultra-distance racing, and fast-paced adventures.
At 500ml (17oz), it’s the perfect size for front-vest hydration—easy to refill at aid stations and lightweight enough to carry without distraction. Whether you’re racing 50km, 100km, or heading out for long training miles, the Ultra 42 keeps your hydration system streamlined and race-ready.
