HydraPak Ultraflask 500ml
The Ultraflask 500ml is so light, you might forget you brought it. Weighing in at 44g, it’s optimal hydration for all types of runners. The pliable material conforms to most pockets and shrinks as you drink to minimise water movement and it can be used with or without the tube.
