    This product is for…

    Runners who want a handheld hydration option for hot weather, shorter runs, or races with frequent aid stations where a vest or belt isn't needed. Also suits those using two flasks for ~1L total capacity on longer efforts.

    Worth noting…

    One host flags that the SpeedFill cap can come undone if the flask is stored inside a pack, worth checking before stashing it.
