Hydrapak says:
The SoftFlask Speed is specifically designed to be compatible with the widest range of vests and packs. Replacement or upgrade, the pinch-welded bottom makes loading into pockets a cinch. Its secure, single-handed SpeedFill™ flip top makes filling fast — both water and fuels — and the self-sealing silicone bite valve delivers sips, not drips. And all this weighs just grams.
Our Verdict
The SoftFlask Speed 500ml fits neatly into vest or belt pockets thanks to its tapered, pinch-welded base and soft material. Weighing just g, it shrinks as you drink to minimise bounce, and the bite valve provides a smooth, drip-free flow. The SpeedFill cap is genuinely useful for quick top-ups, and the wide 42mm opening makes it easy to add powders.
