The Collapsible JavaDrip's clever, expanding silicone cone brews fresh, delicious coffee and yet collapses to just 1" high to travel anywhere. Simply set the filter on top of your favorite container, from a wide mouth water bottle to a small pot, add any brand of #4 filter, grounds and water and voila, eye-opening drip coffee just like home. The convenient cover even doubles as a trivet for the cone when you're done brewing and keeps everything clean during transport.
