Whether it’s trails, rivers or slopes, nutrition is just a bite away. The collapsible, lightweight SoftFlask 250 is easy to fill and even easier to consume with our patented soft silicone bite valve. It can be integrated into a variety of packs, vests, belts, even PFDs. And since it holds 8.5 fl oz of your favorite nutrition concoction, you can go the distance without running out.
Hydrapak's SF250 Collapsible Softflask is the ideal size and material for fitting into long, narrow pockets of running packs, belts and vests. Being soft it reduces in size as you drink, taking up less space in your pack and also prevents the liquid from sloshing around.
