Crazy horse leather is cowhide which belongs to full grain leather and is faviorited by its durability. All products made of real natural leather should avoid water. Please keep the bag dry. If it gets wet, clean the bag with dry soft cloth, then put it in ventilated place to let it dry naturally. The trolley sleeve across the back can hold the leather bag itself on a rolling suitcase, so that you can travel much more comfortably and conveniently to avoid your hands or shoulders from laborious carrying burden.

Build quality is great
Color: Brown
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

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

A good daily driver
Color: Brown
This bag replaced my similar canvas daily bag. I wanted something a bit more dressy to go with my suits and this bag was my pick. Luckily the build quality seems good so far and the bag is designed well for daily use. The leather makes the bag fairly heavy and it will get a patina from scratches, etc. the outermost pocket is oriented sideways which makes sense onf the one hand, but also could be annoying. The laptop pocket only goes halfway up but it still feels secure enough. ... 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

Masa Kawa Warranty
Color: Brown
Update - Masa Kawa provided a replacement and warranty again for the item — thank you for following through on your product support and warranty Update — 3 Feb 24 — as I appreciate the replacement from warranty that was sent, unfortunately same issues and the 2nd leather backpack in 1 year (less than 6 months) falling apart is not acceptable and the quality is not holding up as you can see from the photos. ————/—————————- Kudos to Masa Kawa for the warranty on their product. They provided a timely replacement and I very much appreciate it as that was not expected. Again, thank you and I updated my review. ===========•• I got a lot of compliments on this backpack…I used it for less than 6 months and the shoulder straps are falling apart and fraying. I had a Wilson’s leather I used for 4.5 years…spend your money elsewhere. ... show more
