Salomon Soft Flask 250ml - Quick hydration, zero distraction

Stay hydrated on shorter runs without the slosh and bounce of traditional bottles. The Salomon Soft Flask 250ml features a high-flow valve for quick drinking and collapses as you drain it, minimising movement in your vest pocket whether you're training on local trails or racing.

 

 

Smart Collapsible Design

The flask shrinks progressively as you drink, reducing water bounce that can disrupt your rhythm on technical terrain. This collapsible construction means less movement in your pack, allowing you to maintain focus on the trail ahead rather than adjusting gear mid-run.

 

 

Fast Hydration Access

The high-flow valve delivers quick fluid intake without requiring you to slow down or break stride. Easy to squeeze whilst running, the soft material responds to light pressure, making it simple to grab a drink during intervals or when navigating challenging sections.

 

 

Purpose-Built for Trail Running

Designed specifically to fit Salomon's PREDICT SKIN 2 vest, though it works with most trail running vests featuring compatible pockets. At just 28g, it adds minimal weight to your setup whilst providing adequate hydration for runs up to 90 minutes.

Is the Soft Flask 250ml the right choice for you?

If you're running shorter trail sessions—typically under two hours—where carrying a full 500ml flask feels excessive, this 250ml option offers practical hydration without bulk. It suits runners who prefer minimalist setups, those doing interval training where quick sips matter, or anyone racing shorter trail distances where every gram counts. The collapsible design particularly benefits runners bothered by water movement in traditional bottles. For longer adventures requiring more fluid capacity, consider pairing two flasks or opting for larger volumes.
