Ultraflask Speed 500Ml

Product Information

The HydraPak Ultraflask Speed 500ml is a standout soft flask designed for active pursuits, especially trail running and fast-paced adventures. Its pliable, lightweight design lets it conform easily to most hydration vest pockets, shrinking as you drink to minimize sloshing and maintain a stable, comfortable fit. What really makes it shine is the SpeedFill™ Cap, making quick refills effortless at aid stations or on the go, without the fuss of screw tops.

Crafted for durability and convenience, this flask is built with abrasion-resistant TPU and RF welded seams, so it can handle tough conditions. The wide 42mm opening is a game-changer for adding ice or drink mixes, and the high-flow bite valve ensures a consistent, drip-free experience.
