This largest member of the BeFree Series has a volume of 3.0L and weighs just 100 grams. Its even larger volume allows it to supply larger groups without a problem and is suited perfectly to serve in a mini-base camp or for a family outdoor outing. The integrated bail handle on the nozzle simplifies filling, and the handy grip allows the flask to be carried easily or hung on a nearby tree once full. The BeFree 3.0L version will be available at retail in January 2018.
