The Salomon Soft Flask 150ml is the pre-mixed gel flask — the one that replaces the fiddly sachets, the sticky fingers mid-race, and the litter guilt. Prepare your energy mix at home, fit it into the front pocket of your running vest, and sip through the high-flow valve whenever you need a boost, without breaking stride or fumbling with wrappers.

• Shrinks as you drink — the flexible TPU body collapses progressively as you empty it, reducing bounce and eliminating the sloshing of a half-full rigid bottle. You always know how much is left by feel.
• High-flow valve — delivers a fast, easy sip without hard suction; important when you're breathing hard at pace or when fatigued late in a race.
• 17g total weight — lighter than most single-serve gel sachets it replaces.
• 28mm cap — Salomon-compatible — fits all Salomon caps and accessories with a 28mm opening, including the standard caps across the Soft Flask range.
• BPA and PVC free — food-safe TPU construction with no harmful plasticisers; no plastic taste or odour.
• Pre-mix at home — fill with your own gel, energy drink, or electrolyte mix at your preferred consistency. Zero waste on the trail — no sachets to pocket or discard.
