Customer ReviewsWrite a review
The Knack packing cubes make it easy to get everything I need into my Kanck bag.
I have many "cube" type cases from other manufactures. The ones you make are better, because they custom fit your backpacks! They are much deeper than I thought they would be (so they hold more) but the compression zipper makes them thin enough to take up very little space. But the reason I purchased them is they fit perfect! Thanks for this great accessory to your unique perfect backpack (or in my case it's a briefcase with room for a change of clothes).
Did not expect large size to be small
Well made and nice looking.
I bought my large knack bag about a month before ordering my cubes. I was able to travel with it using packing cubes that I owned before but they were generic Amazon ones. I enjoyed using the bag but decided I needed the full experience and I am very pleased. The quality of the cubes is outstanding. They compress down very well and still leave you room in your bag for other items. They are not as large as I would have hoped however they will do the job of keeping your smaller items together and orderly. I'm a tall guy 6'6 so my clothes tend to take up more space. I'm probably not going to be putting my jeans into any of these bags but for socks and t-shirts they will keep them nice and small so that I can fit larger items just in the Knack bag itself. Plus once you get to your destination you can just take the cubes out and compress your Knack bag down to be your EDC bag and that is what I love about Knack. You can use the same bag in so many different ways. If you are thinking about getting a Knack bag or the cubes I would recommend them. They have been a pleasure to use and have made traveling less stressful on every trip I have used them on.
Light weight but very sturdy compacting that makes packing a breeze. Have had cheap ones in the past but these top them all in ease of use and organization.
Very nice backpack that I can use for the office and travel. I don’t use the chest or hip straps it would be nice if these can be removed. Side handle and luggage pass thru would be welcome additions as well. I thought large may too big but it was perfect for a taller frame.
These Cubes are lighter than air and as strong as can be. I just packed them with clothing and expanded my large knack and inserted all three cubes. Don’t waste time thinking you can repurpose old cubes. Just get these cubes. They are perfect.
