Ultraspire Soft Flask WMX (500ml)

More drinks within easy reach. This soft flask is particularly useful as an extra bottle in the front of your trail vest. With multiple flasks, you can expand your hydration capacity, for example towards two liters for longer training sessions and ultras.

The rounder shape fits comfortably in a front pocket. This makes it handy when you want to carry extra water or sports drink alongside your standard water bottles. You particularly notice the benefit of that extra capacity during long stretches between aid stations.

Choose it primarily for long and self-sufficient runs. If you run short trails or frequently pass water stations along the way, an extra flask is usually not necessary.

Especially useful as an extra water bottle in your jacket.
