For -always Dabei I was looking for a bag that is both not too big and on the other hand, offers enough space for all the things that should have a wife and mother there. It benefited me, that I am already in possession of Interlude of JW and can draw a good comparison. But The Interlude is a great bag, for always there clearly too large. Here the Boomtown comes into play. It offers plenty of space despite compact exterior. Especially the many side pockets (one on the outside with zipper, one interior zip pocket and two separate smaller bags inside, and the outer, smartphone - compatible cell phone pocket) allow the owner to maintain a certain order. But you can also put everything together in the very spacious inside pocket and let chaos reign.
The shoulder strap is adjustable from just below waisted until just under the armpits - depends of course a bit of the size of the owner from. The bag itself is typical of JW. Solid processes and makes a high quality impression. The bag is very light, yet you trust her to also to overcome heavier loads without problems. However, I have not tried already in self-defense. Who wants to constantly carry around 5 kg or more.
All in all, exactly the bag, I was looking for you. From me an unconditional recommendation.
