A well-shaped luggage bag. Do not exceed the sides. Just the right size. The attachment is good. Main zipper protected against rain by a small flap. Perfect for going to the office: I put a pair of shoes, a small purse, my phone, my keys, and there is still room! Only downside: I thought at first to detach easily from and with shoulder, but in fact it's a bit too long to undo, so I leave it on the luggage rack
