Kensington Triple Trek Slim Laptop Backpack for MacBooks, Chromebooks, Tablets & Ultrabooks up to 13-Inch-14-Inch (K62591AM), Black

Many reviews of this backpack, which I've had for nearly 2 years now, state that the bottle holder cannot hold a reasonable (or sometimes any) sized bottle. Included in my pictures you can see that it can indeed hold at least a couple of simple plastic bottles including a 12 ounce BAI tea bottle and a 17 ounce ICE drink bottle. Buy one, wash & reuse. This pouch can be used for ID badges, car keys (a large key ring would fit), several pens or mechanical pencils as well. I believe the Kensington Triple Trek is intended as a commuter backpack primarily for those needing to transport laptops and related gear, I find the 2 bottle sizes suitable. I can make it through a 2 hour meeting with either one, and simply refill before the next meeting or task. The backpack with its main section loaded measures about 4 inches deep at the bottom and 2 inches at the top. Another inch or so would protrude if the front pockets were stuffed. I took a couple stars off since I don't believe this one is really that "waterproof" but likely water resistant. Due to its slim size, many people could simply carry a rain jacket within the backpack and put it on when needed OVER the backpack, should rain come. It's quite professional looking with the brand badge and matching zipper pull are all silver-gunmetal in color. As some have mentioned, the zipper pulls CAN get caught and hung up at odd angles but this only takes a half-second to correct when needed before pulling on the zipper. Another of my photos shows my 14.1 screen sized HP Elitebook laptop. Note the amount of space afforded between the top of the laptop and the top of the backpack. AND, this is with the laptop sitting on top of a 1/2 inch high solid foam piece that I have in the bottom of the laptop slot for additional "drop protection". The flexible velcro strap keeps the laptop in firmly and such straps are getting more rare. In another photo I display the laptop, plus a full sized mousepad in the tablet sleeve (provided additional laptop protection since I don't often use a tablet computer, and a full-sized 1-inch 3 ring binder. Still this section is not completely full. Note: a 1-inch D-ring style binder WILL also fit in between the laptop and tablet storage sections. Included photos show that both my 14.1 screen HP and, a Microsoft Surface Pro 4 will fit together along with a D-ring 1-inch binder between them, OR, with the laptop and Surface together in the same laptop section, still secured by the velcro strap (it's long enough). Did I mention that the Surface has it's "Type Cover" attached? Keeping the rectangular shape of the backpack from top to bottom makes this all possible. Kensington didn't narrow the top of the backpack so much that it would prevent this much lengthwise storage of paperwork and devices. Carrying all 3 of these along with associated charger cables, bricks, mice and such would likely bring the total to over 10 pounds of course! I'm saying the backpack can do it, not that you should...The top front pocket is softly lined like the laptop and tablet sleeves are and measures 6.75 inches deep of usable space by 8 inches across. The bottom front pocket, with 2 pen/pencil slots, a key keeper, a covered slide in pocket (that holds my iphone 13-mini in an otterbox case, and another such slide in pocket with mesh so you can see what's in it, along with additional storage under these pockets and pen & key holders. In total, it measures 7.5 inches wide of usable space and 9 inches depth-wise. I feel that Kensington really maximize the amount of usable space in this smaller and very versatile backpack. Thanks for reading!

This still, by far, one of the best purchases I have ever made on Amazon. Hard to believe I purchased this small backpack 6 years ago. I have used it extensively since, and it still works like new. The only minor aspect that I would have liked to have been a little stronger is the hidden water-bottle mesh, which is a bit torn in places. But given the beating this bag has otherwise taken, I'd say it is a remarkable piece.My main reason for picking this one was to get a small bag for travel & office stints large enough to accommodate the basics (14" laptop, ipad, chargers, phone & accessories, cap & gloves etc) but not so large that I end up overpacking. I needed something that did the job without creating any kind of backstrain. This bag is just perfect for that. Easy to sling over one shoulder or both, well-balanced, and more than enough room. Also super-easy to slip under the airline seat in front of you, leaving enough room for your feet. Looks sleek and slick too. I also like the hidden velcro pocket - great for storing your passport and other travel documents separate from the rest of your stuff. I would happily buy one again if I ever needed to.

Overall: As a smaller woman, I highly recommend this small, professional-looking, sturdy backpack.Size: This backpack just barely fits a 15" MacBook. The main pocket is small, but fits a stack of papers to be graded as well as power cables and whatnot. The front pockets are surprisingly spacious and fit a good array of cables, pens and my phone. I keep a small notebook in the iPad pocket. As a smaller woman I was looking for a backpack that was no bigger than it had to be while still being functional, and this is the perfect size.Looks: Nice and professional. A backpack will never look as professional as a messenger bag, but this is as close as it comes. The material is black canvas and the overall presentation is sleek. I have actually had colleagues ask where I got it. I like the look better than the leather backpack I tried, and it's definitely more flexible. It looks decent even when stuffed full of papers.Durability: Reasonable but not great. I used the first one I got for about two years of very heavy use (and two pandemic years of almost no use). The seams around the front are getting very strained, and look like they will blow out sooner or later; the handle across the top has a small tear. I wish it had lasted longer, but I use backpacks to death, so it's probably to be expected.
