Soft Flask 500Ml/17Oz 42

Built for fast hydration, the Soft Flask 500ml/170oz 42 in Clear Blue uses a high-flow cap for ease of drinking on the move.

A wide 42mm cap on the Soft Flask 500ml/170oz 42 makes it easy to use and clean, while the design means it shrinks as you drink, helping limit bounce at the later stages of your run.
