    Expert Review

    This 500ml handheld soft flask gives you a lot of versatility. My preference is to have it stowed in the back of my belt, but you can also run with it in your hand. It's super easy to refill at aid stations with the SpeedFill cap. I usually start races with one of these full of drink mix and plan to refill as needed at aid stations

    SkyFlask™ Speed 500ml by HydraPak — recommended by Meikael Beaudoin Rousseau

    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.
