Series 1: Large Expandable Knack Pack®

I wouldn't call myself a backpack aficionado but I do have a lot that I seem collect and use for a variety of purposes. I was pleasantly surprised at how much I like this bag. It is now my favorite for work and travel. I have the medium and it is deceptively roomy. I often carry two laptops and this bag seems to gobble them up and still has plenty of room for power adapters, files, other cables, and notebook. that's without even expanding the clothing compartment. It has enough compartments for your various essentials but not too many where you don't know where anything is. Well done Knack.

I have had lots of backpacks. Ones designed for skateboarding and snowboarding. Ones designed with travel in mind. Many for every day use. The Knack out performs them all. Not only is it great for weekend getaways. It performs as an everyday bag with ease. It keeps everything safe and secure with more features than you knew existed. #onebaglife

I got this bag based on a suggestion from a memeber of a Stage lighting group. I was looking for a bag that could hold my large laptop and its peripherals, a change of clothes, and tools or my school books or whatever miscellaneous things I might need. The backpack succeeds in doing all that. Ive used it as a suitcase/travel bag for when I went on a short vacation, I've used it to hold my computer and desk stuff as I was moving into my apartment, and I've used it as I've gone too and from classes. It work great in all those applications and the straps are nicely padded so there was no strain on my shoulders.
My only issue is there are not as many pockets as I would like and the main pocket is just a tiny bit smaller than I would like (still fit my roughly 18" laptop). However, I was able to remedy these issues by using the suitcase pocket in the back.
Overall it is a great multipurpose backpack!

This is my second Knack bag. My first was extensively used during a family vacation across Europe last summer. My wife and kids loved the bag so much I decided to get another in a different color/size for myself. The pouch at the bottom is great for cables and charging cords. Love the water bottle pocket as well, it works for so many things. A quality bag. Worth every penny.

I got this Knackpack when I started my MBA at the Wharton School. I didn't realize what a cool pack it was until I started using it. After a year of traveling across the country for work and class, it still looks brand new. It has been rained on, thrown under airline seats, and stepped on in the classroom. I literally carry it every day, but you'd never know. It holds its form well, protects all my stuff, and has the perfect amount of space to pack for a workday (when not expanded) or a three or four day weekend (when expanded). The backpack that is changing the backpack. Great job, Knackpack!

Great travel backpack. It’s more than I could have possibly wanted. Shout out to Bradley @stuffandthings on youtube for the review which led me to this amazing backpack

I purchased this back pack because there was an option of sizing. As a big man myself I always look funny wearing a backpack that was too small. Having the ability to have a large size it really made wearing it comfortable plus the workmanship of this back pack is unbelievable. From the zippers to the shoulder straps everything is so right and is very sturdy. Lastly the compartments were constructed in such a way that I can carry everything without having to use a carry-on rollaway type case when going on weekend trips. I urge any avid traveler or business professional to get one of these back packs.

I had purchased a medium sized knack pack about four months ago. As a whole, I love this bag for certain reasons:

1. The knack pack could make a well balance of daily work use and expansion of size when I have day out with my baby.

2. It could keep the supere sleekness even I put lots of things inside it

3. Well designed compartment no matter for daily work or baby caring. I used the bottom compartment to put wet tissue, soft pad and some diapers. It quite convenient when my baby has to change diaper

Two points for your consideration of improvement:

1. The key buckle was quite inconvenient to access when I have to take it out or if the main compartment was near full. I suggest to rearrange it at the top of the bag or may be inside the water bottom compartment.

2. It would be perfect for me if the shoulder strap could be hide inside the back of the pack and another handle could be built in either side of the bag which could change to a brief for business. Just like the Forge pack of Black Ember. For consideration of maintaining the sleekness of the bag, the handles (both on top and at the side) could refer to the Evergoods CPL 24. It makes a well balance of sleekness and function of the handles.

This bag is amazing! I am a pedestrian commuter in Boston and was so tired of lugging work backpack and gym bag a mile each way every day. The Large Knack bag solves it all. I can expand and fit full business clothes, shoes, etc for the gym and still carry all of my business essentials (laptop, files, cords, water bottle, lunch, etc)! Recently went overseas, and this bag was fantastic, fits under the seat when not expanded and so lightweight. Love, love, love......

I have owned many, many laptop bags from the likes of eBags, Briggs + Riley, and others. This is the first backpack I've had that combines great looks with great functionality. There are just enough organizational pockets, the ergonomics are great, and it travels well. And if I overstuff my carryon suitcase, I can open the expandable section of the Knack Bag and throw my jacket or extra clothes in there. This bag is a winner.
