Perrine Man Thermos W/Magnetic Lid
This thermos is rad! Keeps it HOT or COOL and the lid has a magnet that allows it to never have to touch the ground, just stick it to the side of your bottle :) Keep all those germs and viruses down. Lets Be Honest, WE NEED MORE HOT COFFEE ;) AND MORE COLD WATER.
They are right about 18oz if you fill it to the brim, and you can easily get over 16oz in there.
