HydraPak Ultraflask Speed 500 ml sport bottle, Malibu Blue

HydraPak Ultraflask Speed 500 ml in Malibu Blue is a collapsible sport bottle engineered for runners, cyclists and outdoor athletes who need fast, convenient hydration. The 500 ml capacity provides a balance between lightweight carry and sufficient fluid for short to medium workouts. Constructed from a soft, flexible material, the bottle compresses as you drink to reduce bulk and fits comfortably in most hands and standard bottle cages. A quick-flow bite valve enables hands-free hydration and fast fluid delivery during movement.

Advantages

The Ultraflask Speed is lightweight and compact when empty, making it easy to stow in pockets or race belts. The soft, compressible body reduces sloshing and allows progressive collapse for a lower profile. The quick-flow bite valve delivers rapid hydration with minimal effort and closes securely to reduce leaking. The Malibu Blue color offers good visibility while remaining understated. Overall, the design prioritizes practical hydration performance for active use.
