For such spontaneous actions like today (discovered in the supermarket a cheap deal on coffee tabs and equal bought a larger amount) the part is just awesome. What in the Carrycruiser no longer purely fit (and that was much good stuff), was allowed to the Mini-Maxi-bag drag.
She then immediately (actually more rain baptism) passed its first test: The Zipp locked the bag completely sealed and the raindrops glistened off on the outside. Therefore My purchases arrived safe and dry at home :-)
I wonder, however, whether it is resistant to tearing ... With today's Shopping finally the breaking point of the pocket was certainly far from being reached.
