Eagle Creek Pack-It Original Packing Cubes for Travel - Durable, Ultra-Lightweight Suitcase Organizer Bags with 2-Way Zippers & Grab Handles, Black, Set S/M

I just used these on a big trip from Australia even though it was a short one. I packed as much clothes as I can and the compression really saved me space in my medium size suitcase. Which consisted of me using two large compression cubes from the normal line and two half cubes of the specter range. The garment folder, toiletries, make up, shoes, hair brushes. Without compression I would have only fitted one full cube inside, I do prefer the original Eagle creek cubes, as I noticed with the specter version even when zipped up the volume was a bit wider.With the original version you can unzip to open up the cube where as the specter only three quarters of the way.

This is the second set of these I've ordered. They are strong and have a good zip. Have had some mmy ones in the past that are lighter and thinner but the zip isn't as good and sometime pulls apart then trying to compress clothes down. These are much tougher. I would highly recommend. I like to use carry on luggage where possible and these will easily mean I can go away for a week without having to book in hold luggage.
