    Would the water bottle fit in the fjallraven kanken 13 in waterbottle pocket?

    Can you use a top made for hot beverages on the standard-neck water bottle?

    Asked by: hallie1
    The flip cap would not fit a standard mouth flask. The only two caps would be the sports cap and the standard mouth flex cap.
