    600ml soft flask

    What can I say!! I purchased two of the 600ml soft flask for my Endurance pack and they are perfect. I use both for fuel and fluid. These guys at Orange Mud know what athletes need. The Orange Mud athletes use every product they sell.

    Perfect fit

    The 600 ml flask fits perfectly in the front pocket of my Orange Mud hydration vest. I can have Tailwind in the flask and 2L of water in back for all my long run hydration needs.

    2-liter hydration pack & add on flask: Big fan of the hydration vest but finally tried the 2-liter Hyde pack. It is perfect! Whether I fill it part way or all the way; it is great! The flask is great as well!

    I love the Hydration pack because it stays more secure when running then the vests. I love being able to sip on the fly.; less to deal with when drinking.

    The flask is cool as well for those days you don’t need as much water, but still want the pack to carry “stuff.”
