Part of Hydrapak’s ultra-light series, the Ultraflask Speed 500ml is so light, you might forget you brought it along on your run. Weighing in at a mere 41g, it’s optimal hydration, no matter what kind of runner you are. Its pliable material conforms to most pockets, it shrinks as you drink to minimise water movement and it can be used with or without the tube. Topped with a new feature, the SpeedFill™ cap, makes aid station refills a breeze.
