It’s lightweight, durable, and incredibly stylish—truly the perfect mix of functionality and fashion. I highly recommend it, and I’m not surprised my friends want one too!

Very professional looking and light weight.

This is a very versatile product with more uses than you may think. Initially when unboxing I thought it a bit too small, but I was completely wrong. It expands on the side and has large compartments and many pockets. You can really use this as a carry-on if you wanted to. I like the size and quality look and feel of this bag. Very well made and thought out well for multiple uses. This can be an everyday bag or used for travel. The water bottle space on the side actually does hold a water bottle without incident. The pictures and descriptions do not serve this product well, if you’re on the fence buy it!

My old backpack was breaking, so I'm in the market for a new one. After a few quick searches, I narrowed my choices down to this one. There's a nice cushioned back compartment for the laptop, as well as a lot of space for other accessories. The backpack is rectangular and I can see this fitting very well in compact spaces during traveling. Lastly, I enjoy the feature of feeding through a cable to the outside of the bag to charge devices as I often forget to charge my ipad at home and realizing too late when I actually need it.The material feels nice and I strongly recommend this backpack for daily use and traveling!

I love this backpack overall. I've gotten several compliments from strangers on its look. I find that is has an appropriate number of pockets and I like its security features. Very practical for daily use. I've had it for 7+ months.I have found one design flaw, however. The current backpack is actually the second one of the same model I have ordered from Amazon - and this design flaw is present with both. Which is: the main compartment's zipper gets easily caught on the underlying fabric flap. It's currently stuck and I may have to resort to some sort of lubricant to get it unstuck - not a great use of my time. The design could be improved by making that fabric protrude less toward the zipper, minimizing the chances of it getting caught.I love the backpack but would love it more if this wasn't an issue.

Bought this for college and it has got so many praises already. Nice anti theft design, easy to access once removed from the shoulder. Perfect fit for kids and mostly adults. Leather material on top and is very durable. Nice build quality and excellent zippers. Yet very lightweight and stores decent amount enough for college or office.

I’ve had this bag for a couple of months and I get compliments all the time. I travel a lot for work and this is my go to bag. I would highly recommend this bag. The build quality is excellent. It looks like it will hold up for a long time.EXTERIORThe exterior is very professional and well made. The large outer pocket is very thin but holds a lot of contents, perfect for a Grid-it type organizer for cables and chargers. This bag fits perfectly under airplane seats. It has a hidden pocket, near the inner hip area, to store your wallet and keys. I carry two cell phones for work and it has a pocket for storing them inside.On the straps there is a place for your hotel key card. I always store one hotel key card in my wallet and the other in the strap that goes over your shoulder. After a log day onsite, it makes retrieval of the card very easy.INTERIORThe bag is cleverly designed and very spacious on the inside. The inner lining has a pro look to it. Unlike traditional bags, it opens up like a clam shell toward the inside of the bag (not the exterior). While wearing it, this bag is theft proof. I can also store an additional battery on the inside and connect to the exterior connector for hands free charging. While traveling on vacation, I was able to store 4 family ipads and they were very easy to retrieve. The interior has a section where you can strap down a laptop and an tablet device.The bag is light and feels good.From someone who logs a lot a miles, I would recommend the bag based on 1) Build quality 2) Functionality 3) Materials 4) Weight 5) Looks. I've gone through a lot of more expensive bags and I would rank this one higher based on the aforementioned weighting criteria.I would highly recommend this bag for road warriors, commuters, and family trips.
