Unlike the typical cooler – even those expensive, heavy-duty rotomolded blocks – the Qool Box relies on vacuum insulation, much like a thermos or hot/cold tumbler.

Long story short, this passive but intelligent cooler doesn’t just threaten to knock off other coolers on its way to the top, it could even replace powered fridge/freezers for shorter trips and events. read more
