In a day and age when you can find nearly anything you want, you sometimes run into a gem amidst the total crap that surrounds it. I have personally looked for a new bag for months while being disgusted with the quality, configurations, material and otherwise lackluster choices made when designing some of these other products. This bag is fantastic. Not perfect, but it is looking very promising after a very close inspection. This review is initial and I will update it as it gets some wear on it. - The first thing you notice is the quality of the fabric; not only does it feel sturdy but it can be said that it is a bit sexy as well with the design print in the front. - Second you notice the quality of the zippers when you start unpacking this thing, opening it up. I have had a lot of bags and these are nice. I do not get that impression or fear you get with others, wondering when they will break. - After opening all the pockets, you see a nice selection of partitioned spaces. The bag I last bought for my programmer (a large HP ENVY 17) was also from here, https://www.amazon.com/gp/product/B00507NAYQ/ref=oh_aui_search_detailpage?ie=UTF8&psc=1. This is a rather popular Targus bag that already has a rip in it from 1 year of use when I hardly move the bag from where it sits. The bag slouches heavily when not zippered anywhere and the organization is terrible compared to this bag. - The orange colored interior is very nice but I didn't get the bag for flash, I bought it for quality. The orange does however allow you to see better where things are against the black color of the outer shell. - The laptop compartment is really neat for making sure the laptop is snug and not moving around. This is the first bag I have seen this on. Once you set the size, you do not have to do anything more than slide it in. Nicely lined pocket, easy to secure. - I just bought an Everki Titan a few weeks ago and the quality is there, but this is a smaller bag. One thing I noticed was that the pouches do not all open up a lot; you have to run the zipper down and then tug the pouch top out a bit to get it open. Not the end of the world and maybe that will loosen up a bit in time. - The larger section is just huge for whatever you would need until you try carrying part of your home along. Bigger things like game systems and external electronics that take some space will eat that pocket up. I am using this for business and have plenty of room for everything. I attached some pics of everything I threw in there and have actually throw some more in after. Can't use it if you don't have it with you. I do not travel by air much anymore so I cannot comment about under the seat storage. By the size of this, i am pretty sure it will fit just fine in the CRJ or Embraer that are still being used by some. Anything bigger is cake. - I did notice a couple things that just irked me a bit but did not make me trash the joint - The front pocket on top does not have any kind of closing mechanism; this pouch is open on the top and although it is pretty deep, if you stack anything that is rather tall, you do have a chance of it hanging right out the top and losing something. If there is not enough pressure to keep the contents smashed in and the bag tips, so may your things. You could argue that if it doesn't fit, don't put it in. That is my thinking but if they just put some quick release strap or even Velcro on the inside to hold it closed, the point would be moot. - There is no real dedicated document slot unless you call that inner zippered see through pouch the document pouch. In what I would consider the "business area" with you cards, pens and such, there is a small square there to hold who knows what. I threw in some very needed guitar picks (just never know), a couple thumb drives, SD cards and a micro adapter. I would rather have had a nice larger square for the passport, tickets and so forth. This is preference but for someone who traveled the airways for 17 years every week, that just makes sense. I am not taking a star away for anything I didn't care for because of the shear fact of how much better this bag is constructed than any bag I have had and ALL bags have had something that either didn't make sense or was not perfect. Yes, it costs more money. If you would rather have quality than quantity, I believe this is the bag. I have another and the quality is there on the titan as well. Some companies just make better stuff. Update 9/11/2019: This bag is still the beast it was when I bought it. Under inspection, I see a very minor stretch under the left strap. This is because I use this strap every single time i grab the bag, which is every single work day into the office or job site depending, and back. Absolutely the best bag i have ever owned. The small irks are still exactly the same. The front pouch that is open; I hardly use it because I do not want to keep track of the possibility of dropping something. If it is small that can dive to the bottom of the pocket, I throw it in. The zippered pocket behind is the same as well. Fully unzipped, it doesn't really open up a ton but you can still see everything and place and take items without issue. I am guessing after all this time that this close configuration is part of what makes this bag stand up to time. I can still open up every single zipper in this thing and the bag stands up. Obviously if you have a weight shift ratio to one side, i am sure you can get it to fall. Straps are in excellent condition for the use of the bag. I might buy stock in Everki as quality matters that much to me.
