Staying hydrated on long runs comes down to how easy it is to drink without breaking stride, and the Silva Soft Flask is designed with exactly that in mind.

Custom-fitted for the front pockets of Silva's Strive Light 5 and Strive Light 10 running vests, this 500 ml flask sits flush against your chest without bouncing or shifting as you move. The soft, rubberised material compresses as you drink and collapses flat as it empties, so there's no sloshing or awkward bulk in the pocket during the back half of a long run. The self-sealing nozzle lets you take a drink one-handed without slowing down or fumbling with a cap.

At 500 ml it carries enough fluid for longer efforts between refills, making it a practical choice for trail runners covering serious distance. Lightweight and low-profile, it adds minimal weight to your vest setup while keeping water exactly where you need it.
