    • Build quality is great Build quality is great
Color: Brown
Review Image by Martin D.
The build quality is excellent. I haven't found any bad stitches or anything like that. I read some comments about the straps breaking after some use, I guess time will tell. The leather is thick and looks like it's going to last long time. The metal hooks to connect the straps are heavy and look good. The expandable part is also made out of leather which is nice. Overall, as good as I was expecting. ... show more

    • Beautiful and sturdy
Color: Black
Bought for husband who drives around and has to carry his laptop/whole life around for work but wanted something leather but still as a backpack. This is sooo nice and has stood up.to his hectic work schedule so far. The extension zipper is very nice. Holds his pens and other small things without sliding out. Counts as a personal item on planes. And they shipp3d and packaged it very well. ... show more

    • 4.5 stars great bag missing a key thing for me
Color: Brown
this bag is really comfortable to use even on long walks. it has really nice padding. the materials all look strong and the exposed stitching gives it a nice look. I get complimented on it a lot. the only thing i wish it had was an option over the shoulder sling for formal meetings. because you kind of can only carry it as a briefcase when in a suit where backpack isn't ideal and i am in those formal situations a lot which means i cant use it unless its the weekend or fridays. ... show more

    • Awesome Real Leather Backpack
Color: Black
Leather, zippers, hardware & most functions are excellent. Only low points are credit card slots & pouch behind them. Slots are a bit too big. But maybe if a RFID blocker sleeve was used they would be fine. And pouch does not have a flap cover. The other 2 pouches in side access area have flap covers with velcro. My 15 pro max & thick passport fit perfectly & very securely. The leather is not called Napa leather but it seems excellent. I wish they made a light color for women. I think my daughter who's a teacher would enjoy this. ... show more

El artículo llegó en condiciones muy maltratadas. Parece que estuvo mucho tiempo en almacén o quizás me enviaron un artículo que ya fue usado o devuelto por la misma razón. Se ven mucho detalles de rasguños, cuero seco, descoloracion. Es una lástima que la marca sea de tan mala calidad y peor aún- falta de control en los artículos que envían. Yo devolví el artículo y solicité la devolución de mi dinero. Cuidado con esta marca! ... show more
