Large Expandable Knack Pack®

Received my bag through Stackry, took me a bit of effort :). What I like:
- overall quality
- look of the bag, not too flashy
- laptop compartment
- small compartment on the upside of the back end
- overall placement of the compartments

What could be better:
- i really miss one "secret" compartment on the inner side of the bag (against my back) to hold wallet on phone securely
- the triangle section compartment - cant really find any use for it?

After doing research for a few months via YouTube and everywhere I could find any information on this bag, I finally pulled the trigger. I am thoroughly impressed in every way. the durability of this bag is unparalleled and the thought put into every pocket, zipper, and insert is remarkable. The way I am able to pack now makes my travel that much easier. I use the backpack every single day, even when I'm not traveling, because there is a place for everything. I hope this bag lasts me a very long time. Everything I can see right now tells me I won't have to worry about another bag purchase for several years.

First, full disclosure, I am a freelance bag designer and was involved in the initial creation of the Knack pack. That said, I am extremely pleased with how it turned out. I've just returned from a 4 day trip (in a sense, a field test) with the large size, and all my clothes easily fit in the clothing compartment. The pack was quite heavy with my clothes, laptop, chargers, etc, but it's very comfortable and carries weight well. The hip belt and sternum strap do a fine job of weight distribution, and the shoulder straps have just the right amount of foam without too much bulk. A small quibble I might have is replacing some of the business card slots in the front pocket (I don't use them, so it's really a personal preference). The only other thing I would change is making more room in the bottom compartment for my laptop charger, it's a wee bit cramped but still works fine.

I would probably not use the pack in daily use around town, but I bought it for traveling, so this is no big deal (and the smaller size would be more suitable for day to day usage).

Great job guys! 5 stars all the way.

It is a wonderful backpack I'm starting to develop some kind of emotional connection with. I use it as edc bag, and have found the use for every pocket. When I go grocery shopping after work, I expand the backpack, and this feature eliminates the need in plastic bags, and I hate to carry weight in my hands. It is super roomy yet slick in compressed form. Build quality is top notch. Thank you for developing this little wonder. I hope it will last for years.

Fully packed in the luggage compartment it easily fits two pair of jeans, 3 long sleeve shirts, 2 pairs of shoes, travel toiletries, socks, etc.
The work compartment fits everything you’d need for work. Plies a place for all items, keys, phones, glasses.
I strapped it on and walked 15 minutes in town - really comfortable.
All that and no bigger than a small roller bag. (With which you’d need a computer bag on top),
