Love this bag! Haven't seen too many reviews that provide much detail on the functionality of the bag (ie. internal design, etc.) so I thought it would be helpful for my review to focus on that aspect.But just to get this out of the way, the bag and the leather are really nice. The color is dark brown, with no shine or gloss. Of the pictures provided on the product description page, the first (showing the entire bag) and third (showing just the handle) seem to come closest to capturing the true color. The other pictures seem to suggest a purplish hue to the brown which is not true to the actual product (probably a lighting issue with the photography).On to the design and functionality. A distinguishing feature of this bag is its "flapover" design. I personally like this design as I feel it adds a certain professionalism to the look, but it will slow you down when getting things in and out of the bag. The buckles are for show; the actual clasp is underneath the buckle and is a metal tab that inserts into a metal slot. So if you intend to access the internal storage of the bag frequently throughout the day and/or if you think it might just annoy you, consider the "sister" bag to this, the Samsonite Colombian Leather TopLoader (the pictures for which, by the way, include a picture of the inside of the bag which is very similar to this flapover bag, just to give you an idea). I like the look of the flapover design and don't feel like the extra second or two that it takes to open up the bag is going to bother me.Once you open the flapover piece of the bag, you'll see that there is an unzippered, unvelcroed compartment on the front side of the bag (which is covered by the flap when the bag is closed). Inside that compartment are places to store business cards, pens, and a compartment big enough to hold an old style flip phone cell phone (about the size of a deck of cards). Also inside this compartment is a zippered compartment that measures 12" wide by 5" deep. So this front compartment is meant to hold your small stuff, keys, flash drives, etc.On to primary storage. There are 2 main zippered compartments that comprise the bulk of the bag's storage. The larger of the 2 zippered compartments is towards the "front" of the bag (the front being the side with the buckles), and the smaller one is towards the "rear" of the bag. The larger compartment is padded on all sides and has a middle divider so that you can place 2 15" laptops into the one compartment, separated by the divider (I tried, and they fit easily with no issues zipping everything up; my laptops are Lenovo Thinkpads and are of average size for a 15" laptop, more likely on the big side)(note: to be clear, this compartment is designed for one laptop, but is big enough for 2). There is a velcro strap in place to secure a laptop for one of the divided sections of this compartment. The floor of each divided section is flat, about 1" wide. Also in this larger compartment, on the "front" side of the compartment are 3 unzippered, unvelcroed pockets that are about 5" wide, 7.5" deep and 1" thick. They are big enough to store AC adapters, spare batteries, and items of that size. I have an oversized checkbook carrying case that fit in easily with room to spare. So you can see this one zippered compartment has a lot of storage space (more than most messenger bags for example, and with more padding).The 2nd zippered compartment is on the "back" side of the bag. It is big enough to fit a 14" Lenovo laptop. A 15" inch laptop would be a tight squeeze. Note that this 2nd compartment is not intended to be the compartment to carry your laptop in, I am just giving you a sense for size and dimension. The walls of the compartment have padding on both sides, but the larger compartment discussed above seems to be the primary storage space for "fragile" electronics (the larger compartment is also in the very middle of the bag, surrounded by other compartments which creates additional padding and security for the protection of the laptop). You could put a tablet or small laptop in this smaller compartment but I'd use a sleeve (not provided) to add protection. This compartment is primarily designed for paper items, folders, notebooks, etc. The floor of this divided section is v-shaped (not flat like the bigger compartment).Lastly, the "back" of the bag (the part that would normally sit next to your body) has an unzippered compartment that runs the length of the bag, with a velcro fastener inside in the middle of the compartment. This is where you might put items that you want quick access to, such as printed itineraries, newspapers, e-readers, etc.The shoulder strap is dark brown nylon with brass colored hooks. The pad itself is leather on the outward facing side and some sort of synthetic material on the shoulder contacting side. I've seen some reviewers lament the fact that its not a full leather strap, but at this price point, I think nylon is to be expected. The colors all match and it seems to fit the bag. Another reviewer mentioned you can buy a leather strap here on Amazon that may work (Winn Harness Leather Shoulder Strap w/Large Ergonomic Shoulder Pad).Overall I am impressed with the design of this bag. It's big enough to be functional for a mobile professional or student, without being too bulky (at least not to me; I have seen a few reviews by women on here that say the bag was too big for them). It's not a "slim" laptop bag, but it's not an oversized one either. Right in the middle of the spectrum.So, great looking and functional and at a great price point. Very happy so far. The only unknown right now is long term durability. I'll try and update this review a year from now.
