Large Expanding Packing Cube

I prefer these to other compression cubes in that it has a structure which helps the compression and better fits together with other knack cubes than the formless ones of other brands. The zippers are well made and can handle a tight compression. I was able to fit five rolled up shirts plus briefs and a pair of socks. When I use my Knack series 2 medium bag it fits nicely in the main compartment when I don’t need the expansion. Great price for good quality.

It’s a packing cube. It helps manage space in my pack. .

Since it is designed especially for my bag I couldn’t be happier with how it is holding up to all the items I put in it.

Excellent cube, I really appreciate the breathability of it. Wish it was about 30% bigger though to make the most of the compressibility!

Excellent quality, tailored to perfectly fit the suitcase compartment of the Knack Pack. Very durable yet lightweight, and compresses really well - managed to store 4 T-Shirts, 1 Pajama set (shorts, top), 1 convertible pants and a hoodie. Paired with the medium packing cube which had my underwear (boxer brief and socks), I had enough clothes for 5 days, which really is forever if you wash them!
