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!
