Quality product seldom seen.

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.

almost perfect

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.

You must order the Knack Cubes. You must.

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.

Great packing cubes

They do what they are supposed to, and they compress well. The cubes have a certain rigidity on the outlines, which for me is great. Most packing cubes just plop down when opened and empty.

The bundles provide great savings, but I would recommend just getting two large ones, regardless of the Knack bag size you bought.

Compress is very well.

These compress to extent that it will not even fill up a large knack pack. You still have enough Room to put a couple of light jackets on top of it would plenty of Room to my read and put a pair of pants.
