Very well made, looks terrific, the inside bright fabric makes it easy to find things and it's very comfortable. Loved mine so much I bought one for my husband for Christmas.

The back pack is well made and has great fit and function with the expandability.

Got this for a trip to portugal and it was perfect. Love all the compartments, helped things keep very organized

A pocket for every purpose provides a way through your pack without unpacking the whole darned thing. It’s space and weight efficient. It allows me to use for work—traveling or a day at work. Great weekender. . Exceeded my expectations.

I love this bag for more than just travel!
My company has implemented a flexible work schedule which means I am in the office a few days a week and home for the rest. However along with the flexible work they have also added desk sharing called hoteling. This means that I no longer have a permanent desk to work at and I will need to reserve my desk for the days that I am in the office. This is where the Knack bag comes in. I am now having to carry a mobile office in my bag. Not only do I bring my laptop for work as well as a tech pouch for all the various dongles and power cords that laptop needs. I also bring my own keyboard and mouse. Since keyboards and a mouse get pretty gross anyway not to mention the risk of germs spreading, so having my own just makes things a lot more sanitary. The bag also holds my water bottle, my lunch and my shoes (I wear street shoes to and from work because the winter weather will ruin a pair of dress shoes quickly). The bag handles all of this without having to expand it. So if I need to bring a sweater or gym gear for after work I can just expand my bag and fit whatever else I need. In one bag! I see so many people ,especially women, carrying multiple bags into the office it is amazing that they don't have shoulder issues. I also really enjoy that I am hands free with the backpack because I can then open doors for others or pick up a coffee on the way in without dropping anything. With my Knack bag I know I have everything that I need for a successful day at work and with the professional look of the bag I don't feel like a school kid who walked into the wrong building. When I purchased this bag I had visions of traveling with it and it works really well for that but it has so much more versatility that just travel. I'm really happy with this bag and I'm so glad that I have it as my mobile office.

I've been holding back on a review to test this one properly, but after about 18 months I can conclusively say - this is the best backpack I ever owned, and in terms of frequency of use - probably the best piece of gear of any kind I've bought, ever. In these 18 months, I've used my medium-sized Knack Series 1 to..

- Carry my laptop + my gym gear (shoes and a change of clothes) + books on gym days. Sleek and comfortable and looks better than most backpacks.
- Carry my laptop, several books, a smoothie bottle, the Knack water bottle AND 60m of climbing rope AND harness AND shoes, AND goggles AND swimsuit on climbing + swimming days
- Travel to Iceland, Africa, Middle East, and the West Coast - on trips ranging from 4 days to two weeks - always using the Knack as my only bag, carrying everything I needed for hiking AND working AND formal occasions.
- Everyday use, from meetings to shopping - obviously.

Only quibbles:
- The little pockets in the front compartment are quite unnecessary - who would put their credit cards there?
- Would be great to be able to purchase a detachable waist belt as well as a chest strap - when overloaded to the max, the pack does tend to chafe on the lower back.
- A rain cover would do wonders too, although so far the bag has been pretty elements-proof.
- And last but not least - PLEASE start delivering to Europe! The bag is the envy of half my UK friends and they'd be lining up to buy it if it sold here.

I am a student and have loved using this bag. I bike everywhere and that includes the grocery store. Being able to go directly from classes to the store, expand my backpack to fit all of my groceries, and continue on with my day has been a considerable time saver and incredibly convenient. I will never buy a daily backpack that doesn't expand now and I plan to stay with Knack!

I purchased this backpack to take on my trip to Ireland. Great compartments for chargers, toiletries, medicines. Love that the large compartment unzips like a suitcase so that you don’t have to dig for what you are looking for. Very pleased with everything! My new go-to backpack!

I used my Knackbag on a trip through Asia. It was the perfect size to carry additional items that could not fit in my carry-on. I highly recommend this product!

Exactly what I was looking for. Not too large but still fits everything needed. Excellent design.

I plan to use this item on my my business trip and expect it'll be a great replacement for my rolling carry-on bag!

Good product

I love this bag so much, it nails everything that I wanted. However the downside is the weight of this thing. Without putting anything into it, it is already heavy.

If they trim the weight then it would be the perfect bag for me.

Perfect!

Muy elegante y con suficiente espacio para organizar.

Great bag and I’ve had many. Best bag for style, function, expandability etc. being a designer, this one always looks sleek and great even with a suit. My knack bag logo has popped off on 2 bags unfortunately, improvement needed there. Laptop zipper placement placement needs to be reversed to top of bag as laptop always sticks going in. Have to always manually move shoulder strap and really push zipper open. Not huge hassle but bothersome for quick in and out.
Weight is great. A bag is a bag, it’s only heavy based on what YOU put in it!

As anyone who knows me will tell you, I am OBSESSED with bags. For decades, I have looked high and low for that one bag that puts the search to rest. The Knack bag is that bag. It easily handles my everyday carry needs - and I carry a LOT. We're talking laptop, tablet, headphones, tons of chargers and cables and power supplies, personal items, keys, wallet, pens, notebooks and journals, and most days, a packed lunch and some snacks - and of course my Knack water bottle, which fits perfectly in the side pocket and doesn't hang out in some lame mesh pouch that makes me look like a hiker or a college student. The back is deceptively roomy while also being sleek and stylish enough to confidently carry into work meetings. There aren't dangly bits and a bunch of clutter, yet there is a pocket and place for everything you can imagine. AND THEN, as if this were not enough, there is the expansion that easily lets me pack for a long weekend trip. The packing cubes are like magic and allow me to maximize the space. Even loaded - and I just recently had this bag loaded and then some on a work trip, it was comfortable to carry, especially with the removable chest strap. I love that it slides on my suitcase handle, and even though it does so sideways, everything stays in place. The materials feels like high quality, the stitching is excellent, and it is a substantial, beautiful piece that never fails to get compliments. Oh, I went for the teal color, and it is really beautiful. It's bright without being obnoxious, and it gets compliments everywhere I go. This bag is one of the best investments you will make. Take it from someone who now owns two of these bags (I like having color options). If you are a commuter who carries a good of stuff, and you also want a bag that you can throw in 3 or maybe even four days' worth of clothing, Knack is the way to go.

I love this bag, but it gets too heavy when expanded and packed out for how thin the straps are. Would be the perfect all-in-one bag if they just made the medium version have a removable hip belt like the large.

Absolutely love this bag! It was a little pricey but it has held up very well so worth it. I use this bag every day for work at the hospital and then take it on trips with me. It still looks brand new and I’ve had no functional issues. It fits under the seat on delta flights so I’ve had no issues using it as a personal item. Would buy again!

A great bag but I with I boghut the gray one!

Only good if you need it for work. I love it but it wouldn't work for what I need.

Absolutely terrific backpack. It holds an amazing amount of stuff in a very organized way

Very nice , small though even for 1 class definitely probably more for a working Nurse Love it tho and the color!!! Will be buying a bigger one for next semester!

Bought for a 12-day tour of Germany, I found this bag to hold all I needed as a carry-on. It fit easily under several different plane seats as advertised. My sunglasses and water bottle did not fit in the designated pockets, but I was able to pack 2-3 days of clothes and toiletries (just in case) as well as tech cords and adaptors. I highly recommend this Knack Pack. As I am only 5' tall, the small size was perfect.

This pack is so well-designed. Every compartment is just perfect for the things I want to take on the plane, and then for using around town. The expandability feature is also well-designed. You can actually carry a few items without having to expand the compartment, so you maintain the lower profile. I carried a rain jacket and another light jacket. I love it so much I even bought one of the suggested water bottles to use when I carry it out around town sightseeing. AND THE ZIPPERS DON'T SNAG!!!! Great design and great quality.

Just received my Series 1 medium Napa leather bag. Love the bag, but the expansion zipper is missing the handle to pull the zipper. Would have been a five star review otherwise. Wondering what i should do?

So I owed a leather bag from ebag. The leather is no where near my new knack bag. I was concern about how my new knack bag would travel. The bag is comfortable, I purchase the additional harness belt for 10 buck on a whim, great purchase, nicer than the provided one. While my precious bag had crazy amount of storage this bag has plenty and it more functional. Really enjoy the hidden carry on section. Brilliant design. Built to last. Brought on a whim on sale. Worth every penny. Been researching bag for a while. Giving away two bags for this one. If was fun to take a bigger bag and put all of the stuff in this bag without expanding. Thanks Again Knack!!

I was skeptical, but, as advertised, I've managed to pack for 2-day weekend trips even in the winter where the thin shirts are replaced with fleece quarter-zips. And while it looks bulky when filled, it's still comfortable to wear and walk around with.

My only issue is that the leather is so nice and soft, I'm worried about taking it on work trips (construction sites) or checking it on a plane (if needed). I may need to get a second pack for such trips and save this one for weekend adventures.

Wonderful backpack , very classy with adequate compartments. Great finish. Would highly recommend everyone getting one !

This is my second medium Knack, but my first
made of leather. The leather is definitely worth the additional money. I love my first bag, but this one takes it to a whole new level. Same functionality as all the other Knacks, but the tactile qualities really communicate the capability and luxury of the leather option. Sleek and strong...it doesn't get any better than this.

I liked the multiple ways to carry this item, and its size will be helpful on future flights!

I love the new bag. It does everything. The only addition would be a front zipper flap to quickly access important items.

The Sling Bag is a life saver! It's not bulky, has 2 great compartments and light to carry. Truly recommend it!

I bought this bag to carry my camera on hikes. I love it. I can carry my camera and water and it's perfect.
