Great Price, Great Backpack
Color: Black
Size: 17.3 inch
Took this bag as my carry on to the UK. It’s well made, seems durable, water resistant and travel friendly. All the compartments make it easy to stay organized. It has much more space than I needed, but I was grateful to have it. The padded straps make it super comfortable to carry, especially on planes, trains and other transport. It has cinch straps on the side that help keep it slimmer if it’s not packed full. It also has a strap to fit on your suitcase handles. (I honestly didn’t need a backpack this large, but a smaller bag by this brand is quilted in front and I didn’t care for how it looked). It did not fit under the seat in front of me, but to be fair, I flew British Airways business class and the space was about half the size of typical US airlines. So it should fit domestic flights no problem. There’s a hidden side pocket which is nice. The eyeglass compartment is good if you don’t have a sturdy case, and is easily removable if you do. The rechargeable cord is a great feature. One minus point -the lock it came with seemed kinda weak so I didn’t bother using. All in all I’m really happy with my purchase. We bought two for our trip. For the money, you can’t beat this pack! .

Great pack for day use or extended trips
Color: Black
Size: 17.3 inch
I used to travel a lot for work and became a backpack snob. In fact, in professional forums for my job, the best way to get a long thread going was to ask what people's favorite travel backpack was. I've taken this to other states. This has flown with me on work and family trips, and it's my daypack when I need to carry more than my smaller messenger bag can handle. I've given a good dozen alternatives a test, yet still none seem to match the combo of utility, capacity, and comfort this offers. First Pro: TOP POCKET. Seriously, the perfect place for a few quick-grab items (sunglasses, ear buds, reading glasses). This is a feature I've become addicted to. It's so useful on planes as you just need to be able to reach the top of the bag to access it. Second Pro: MOAR POCKETS. The main compartment has added laptop and tablet pouches. The second largest compartment has an additional open pocket and a large zipped pocket. The third compartment has a variety of pockets (good for a notebook, pens, business cards, etc.). The fourth compartment has a divider inside. Then there are two zippered pockets on the sides with mesh pockets on the outside. Last a "hidden" pocket on the back. Third Pro: COMFY. The padded back and straps are comfortable enough for extended travel. Fourth Pro: STURDY. No rips or tears or loose stitching after 18 months. Plus a sturdy handle. If I'm really pushing the volume on the side pockets, I can clip my metal water bottle to the handle with a carabiner. Cons: Wish the luggage strap on the back was a little higher for better balance on my roller bag. A little too easy to overfill so it needs to be shoved under a plane seat instead of slid. I've tried a variety of bags at a variety of price points. This hits the sweet spot as it's one of my favorite bags and beats out more expensive ones.

Great Quality, Lots of Room and Compartments
Color: Black
Size: 17.3 inch
I’ve been using this backpack for a while, and it has been my companion when traveling. It has plenty of room, multiple compartments, and makes it easy to keep everything organized. I liked it enough that I purchased a second one for my daughter as well. It has held up well with regular use and has plenty of capacity for work, everyday use, and travel. Overall, it’s a good, practical backpack.

A 1st class moderately large backpack at a great price
Color: Black/Grey
Size: 17.3 inch
What an absolute bargain! Attractive and functional. I have reviewed dozens of backpacks of moderate to large size and none come close to what this Kroser offers for the price. Stitching heavy duty. Outstanding construction starting with a sturdy padded thick nylon handle on the top PLUS a 1/4" plastic covered wire cable attached end-to-end with ferrous metal end pieces with a rivet into the thick nylon fabric. I counted 10 pockets inside and two on the outside for tall water bottles that likely won't dislodge easily. 2 compression straps to restrain the backpack snug under the Airline seat. The shoulder straps are wonderfully padded, well-padded back part for added protection. Chest strap too. I haven't filled it yet, but I did put in several paperback books, my 9-10" iPad, some wood flutes in their fleece case and my iPhone into an inside pocket connected to my solar power pack via the built-in USB power connector. There's still plenty of room to put in toiletries, shirts, shorts swimsuit, underwear, and maybe even some sandals. It also came with a small three digit combo lock that's not much help if the whole pack is stolen. It's the thought that counts. I do believe that this gem will last a long time and I highly recommend it. The price point was amazing compared to some of the higher brand names advertised. It is made in China, but it's got to be in the top 1-2% of Backpacks that come from Asian sources. Disclaimer: I received no compensation for this honest review. If you are a small frame person, it would probably be too large, but it sure holds a lot. I'm 5'9" and about 175#. Looks: Great Why did you pick this product vs others?: Size and roominess, fabric and construction quality, sturdy handle, comfortable, shoulder straps, etc. Waterproof: Yes Rip resistance: Yes Travelability: Yes Straps: Wide and padded Organization: Lots of pockets, lined

Kroser 17.3 XL Computer Backpack vs Targus Drifter II
Color: Black/Grey
Size: 17.3 inch
TLDR: The Targus is a very good laptop backpack, but perhaps not twice the price better. I’ve used a Targus backpack for over 6 years, mainly to carry my laptop to work and back, on average over this time period around 3 days a week, walking around town, on the metro, uber rides, etc. I’ve also taken it with me to after-work happy hours, bars, as an overnight bag, etc. During this time it has been an exceptional backpack, however one of the suspension straps finally broke on it, so I decided to try this Kroser as an alternative. The following is my assessment of the differences between the two. Weight: The Targus is lighter than the Kroser, but the Kroser is slightly better padded overall. Handle: The Targus has a rubber wrapped wire handle, while the Kroser has a padded cloth wrapped wire handle. The Kroser’s handle is more comfortable. The Kroser also has a cloth hook which the Targus does not have. Color: I bought the silver / black Kroser. While you can’t really tell from the Amazon pictures, the Kroser “silver” color is a *lot* darker than the Targus silver. In fact, I’d even call it almost dark grey, not silver. (See the "Wenger Synergy Backpack, Gray" listing for what it actually looks like in real life) Reflective: The Targus has reflective piping on the back. The Kroser does not. If you are afraid of people not seeing you at night, or might be peddling on a bike at night with this on, you might want to consider the Targus. The Targus also has bright yellow loops throughout while the Kroser has darker red loops, and fewer of them. The Targus also has silver zippers, rather than black, and silver grommets on the back. Overall the Targus is a lot more visible than the “silver” Kroser. Side Pockets: One of the reasons I loved the Targus were the two side pockets, where you could fit a water bottle or a mini umbrella and zip the pocket all the way closed. You cannot do that with the Kroser, its pockets are about 2 inches shorter than the Targus’. Even a mini umbrella will still stick out of the top. The Kroser does have the cinching / compression straps that helps keep things like this in place, but the Targus did not even need these. Also, I can definitely see these compression straps being a future point of failure, as other reviewers have mentioned. Back Padding: The Targus is good, but the Kroser is a little better, and this is probably part of why it weighs more. Aeration between the two seems similar. Internal Padding: The Targus is good. I’ve never had any laptop or electronic item break inside my backpack, and I’ve taken it everywhere. But the Kroser is admittedly _slightly_ better. Still, they're both good. Bottom Padding: While the Targus has a rubber-like base, which is better for putting down the backpad on a wet surface, like a bench, the Kroser has slightly more padding, better for protecting items in the backpack. Your choice as to which is more important. Back Straps: Both seem similar and equally padded. The Kroser does have the chest strap, which the Targus does not have. But the Targus has suspension straps, which the Kroser does not have, and which _might_ make wearing the Targus a little bit more comfortable over time. Top Pocket: For the Kroser this is truly only the size of a glasses case, shallow. It's padded, but it's small. The Targus’ on the other hand is almost too deep, you can lose items in there, have to go fishing for things. Inner Pockets: Honestly the two are almost identical in terms of inner pockets, pockets-within-pockets, clips, hidey holes, etc. I really don’t see much difference in terms of places to put things on the inside. One moderate difference I will point out is that for the main (non-laptop) compartment in the middle, the Targus has this too large “kangaroo” pouch inside of it which often got in the way of me attempting to put something into the main compartment. The Kroser has a tighter version of this pouch which does not get in the way, and does not have this problem. Zippers: The zippers on the Targus are good, but those on the Kroser are a little better, smoother. Sum: Honestly they’re both very good laptop backpacks, and about the same size. Not taking into account cost, I don’t really see a clear winner between them, depending upon what you need. Taking cost into account, I think the Kroser is a mostly comparable backpack for about half the price. As long as you don’t need to be seen at night.

Hella durable!
Color: Black
Size: 17.3 inch
Built ruggedly tough. I abuse backpacks. I typically carry about 15 pounds to work and home every weekday. I throw, toss, and whip backpacks across the room, into my car, and sling them onto my back by the arm. This bag has withstood all of that without so much as a frayed thread. Impressive! Aside from its durability, I also like that there are a ton of compartments in this bag. I use the sunglass case to protect a chip I need to work, the lower back compartment for specialized pens, and the other eight pockets (external and internal) to organize so much stuff. It doesn't have an insulated compartment, but that wasn't what I was buying it for. It has held up well and helped me carry out my work without problem. Still haven't used the charge port, but it's nice having the option if I ever do decide to.

The best budget bag!
Color: Black
Size: 17.3 inch
To preface this review, I have at least a dozen other bags, been hunting for that perfect one. I'm now looking at bags that are in the $200 to $300 range. For right now though, this Kroser is my current favorite. It's got lots of pockets for organization, although it's sorta generic. I like the zippers, especially the one for the laptop compartment, chonky and smooth! Also, it self stands if you pack it out right! (A self standing bag is one of those things you don't think about, but once you have it, you don't want to go back). It holds both my laptops, my pouches, notebook journal, and still has space for my sweater and other stuff. If the compartmentalization was less generic, and the materials higher quality, and the interior liner a nicer color, it'd be the perfect bag! (Pro tip, if you are picky and want things like higher quality materials, more thought out organization, etc... that's when you're in the high end bag game and looking at stuff like Pioneer Panda or Tom Bihn Synik). But for the price this bag is a steal and I'm so glad I have it!!
