I know this thread is old, but I just ran across an empty one. Here are more details: Starbucks calls it the "Coffee Traveler." The stated capacity of coffee in the box is 96 fl. oz. (2.8 liters). Unfolded as shown out of the box, the bag holds about 180 fl. oz., (1.4 gallons or 5.5 liters).
The lid doesn't seal well. It appears the gasket is too thin. This looks to be an easy fix.
Empty weight (wet) is about 2.5 oz.
