HydraPak - Ultraflask Speed 500ml

Part of the ultralight series, the Ultraflask Speed ​​500ml is so light you might forget you brought it. Weighing just over an ounce, it's the ultimate hydration no matter what type of runner you are. Its soft material fits most pockets, it retracts when you drink to minimize water displacement, and it can be used with or without a tube. Topped off with a new feature, the SpeedFill™ cap makes refilling at pit stops a breeze. Ultra light, ultra useful.

• Comfortable Fit: Soft material fits most hydration vests, belts, or backpack pockets.
• Compressible: Flexible design shrinks as you drink, reducing water displacement.
• Customizable hydration: Choose between bite valve and drink tube cap.
• Speedfill Cap: Flap cap for quick filling at refueling stations.
• An ideal complement or replacement for your running vest, bag or belt pocket.
