Travelling? This is perfect for you. A perfect posture black diamond design bag. Its back flap is cleverly stitched there for it to latch on to your suitcase and sit pretty there. See pictures ( Sorry,the suitcase is not included!) No more lugging a large bag on your shoulders or putting it on the floor at airports or stations. Its base is hard and sturdy while its large soft body embraces almost 15 inch (base) by 10 inch (height).
