Professional and streamlined leather backpack
I’ve had a dozen or so backpacks to use for work (corporate environment), and I really love this one. The leather is of high quality, plenty of pockets, strong zippers, straps, and grab handle, and provides a polished, professional, well-put together look. In the rear, zippered compartment, I have a 15-inch HP laptop, an iPad, and a 1/2 inch notebook. The main compartment is spacious and holds chargers for each device plus a lot of other miscellaneous items. There are two front, zippered compartments (one is intentionally “hidden” behind the other) that offer a secure and accessible way to access smaller items like pens, air pods, keys, etc. Great purchase, and I would definitely buy it again.

Love it!!!
Color: Mocha Brown
I bought it because it's the perfect size for carry-on luggage on the plane, and it's big enough to carry several things. Excellent quality for the price. It looks super cute and goes with everything.

Lots of storage but compact look
Color: Mocha Brown
I was looking for something for my corporate 9-5 and was over a tote bag. This is perfect! It fits so much without it feeling or looking bulky. Love the amount of storage it has and I think it would even be a good travel bag
