Started using cubes for packing several years ago and you can't beat them. Bought the medium and small sizes of these eBags and they are perfect. Durable, light material with sturdy zippers and the mesh helps remind you what you packed in that cube, course I also use colour coding. I find the medium and small size eBags are the most useful sizes -- I use the medium ones for larger or bulky clothes (pants, shorts, sweaters, etc.) and the small size ones for tees, socks, panties, scarves, and just about everything else. I have some of the long narrow ones too and they are good for accessories. My go to luggage are roller duffel bags -- I have a large one and a carry-on size. Using packing cubes makes packing and unpacking so much quicker and it's way easier to stay organized, even live out of your suitcase. If I unpack, I just transfer the cubes into the drawers or cupboards. Works great too when you have to share luggage or storage space. My order came fast as usual. Thanks, Amazon!
