Review on Efficiently Pack with Amazon Basics Packing Travel Organizer - Essential Travel Accessories and Organizers by Jodi Johnson

I used these on a recent trip to Scandinavia and they have helped me keep my backpack organized. The cubes are really flexible, but they take shape as you fill them. I liked that I could fold them or put them in my backpack after I filled them. I haven't had any problems with zippers and none of my cubes have broken after two weeks of regular use. The zippers don't look high quality, but open and close without jamming. My photo gives you an idea of how big each cube is. In fact, I used a large cube for pants, a medium cube for shirts, a small one for underwear, and a long one for socks. I wanted a more established brand but settled on Revain Basics as they are a bit cheaper. . So far I'm really happy. I'll use them for a few more summer trips and post updates if anything changes. UPDATE (12/2018): After 2.5 years of use they are holding up very well. I've used them on 5 international trips and several domestic trips and haven't had any breaks and the zips still work like new. My wife wants a set immediately.
