I love my Knack so much that I bought another for my husband, so that we can run away on adventures with just the one bag. These are so beautiful. Well-made, solid construction. Intelligently designed. These are my favorite bags.

I love my bag. I bought it for a short business trip to keep things simple, but I didn't know how much I could carry in it; I had two days of clothes, a laptop, a camera, and some accessories. It is amazing. Now I'm planning to take road trips, long weekends and I can wait to pack my stuff in my Knack bag.

this bag fits so much more than it says in the description! it is amazing and so well built, the quality is better than I thought it would be for sure!!! I was a little hesitant about the price but I couldn't be happier that I took a chance!!!

I cant say enough things about this bag and the company it represents.

Not only is this bag incredibly functional and sleek, but the team also have the best customer service.

I needed this bag quick as I was heading out of town for a very important business meeting. The problem is I purchased this bag around an holiday weekend.

Nevertheless, the customer service team pulled a few extra strings and ensured I got my bag within a business day.

And this bag truly is "sleek and sexy professionalism meets extreme functionality".

Only my highest recommendations!

Short version: Order a KnackPack now and thank me later. 
Long version: I studied backpacks for six weeks before buying one. I am an avid RedOxx bag owner. I own six bags of theirs. I could not get over their backpack looking more a hiker than a minister and missionary.

I found Knack through reviews. I bought the large. I could not believe the quality or the spaciousness of the bag. 

I put it through a 12 day trip only carrying my tech. I loved it. I did not unzip the expansion section. It was perfect for plane and car and coffee shop travel. I came home; I did two, two-night trips with my suit packed. The suit did not wrinkle. It fit the overhead bin even with the expansion pack unzipped on a 900.

Great customer service by Rachel. I had two minor cosmetic concerns. She responded with grace and exceeded expectations. 

I wholeheartedly endorse this bag.

This Knack Pack is well put together. Everything has a place and kept very neat. At the airport two people asked me about it. I saw one other Knack Pack and it looked good .

I thought the large size would be too big but it's actually very comfortable and fits everything

Expectations are the same as reality! The pockets and organization do their job well. It IS VERY sleek when in compressed form. The large one looks very good on a 5' 11" person, even on someone a bit shorter than that. The material is great, the look is great, the top handle is great, the capacity is great.

The triangular front pocket is a bit awkward, but still functional. The sternum strap cannot be removed, and you can end up with a lot of dangling stuff.

I am a flight nurse in the Air Force and take frequent overnight trips... prior to this bag, I had two choices: 1. mix clothing and equipment in one large compartment, or take two small bags; however, thanks to the Large Expandable Knack Pack I can pack a change of clothes... a spare flight suit... and all the paperwork/equipment I need to complete my mission. This is the best "flight bag" I have used!

I have been extremely happy with the purchase of this bag. Love how the main and front triangle compartments fold open, giving a good visual of the contents without spilling anything. It has the feel of handing you it's contents which combined with the smooth zippers that can be used with one hand, I can get what I need blindfolded. The amount of space is perfect for my daily carry where there is just enough space for an extra sweater or jacket. The expansion gives exactly enough space for my 2 packing cubes and toiletries. I do wish the bottom compartment was big enough for a pair of shoes. I don't want to put my laptop cable there as that is a 3rd zipper then to get my laptop setup but it's too small for anything beyond a pair of flip flops.

Comfortable but the back panel gets sweaty on my bike rides to the office. The off center hip belt is also kind of annoying and just barely tightens enough for my 30" waist. Also the chest strap needs an elastic to hold the excess strap so it's not bouncing around while walking. Shoulder straps are great. The clips that hold them on are really nice and can be used to hold excess strap.

Overall I really like the look. The grey was a bit darker than expected but I like even more than the pictures. It just looks good sitting there in my room. It would be nice if it stood up on it's own but it's solid enough to lean against things really well.
