Hydrapak's SF150 Collapsible Softflask is a small, lightweight and collapsible gel flask with a high flow nozzle. Ideal for running hydration belts or vest pockets.

Hydrapak says:

SoftFlask vs. gel packets = no contest. Simpler, faster and cleaner, this lightweight 150 ml collapsible gel flask allows for instant nutrition on your most challenging expeditions. Just fill it with up to 5 gel servings, squeeze it empty and you’re ready to take on the world.


Hydrapak's SF150 Collapsible Softflask, is the ideal size and material for fitting into small pockets of running packs, belts and vests. It can hold up to 5 gel servings which is more convenient then having separate gels all over your pack which are hard to get at while your running.

Unlike the other HydraPak flasks, this one features a high flow nozzle instead of silicone bite valve, allowing the gel to flow more smoothly.
