I have a smaller set of packing bags that I love. They make packing for a trip much easier, and I just take them out when I get to the hotel, and slip them into the drawers. These, however are even better! They are much larger that the ones I have and will fit larger items like shirts and shorts. Packing bags are great for items like socks and underwear that scatter everywhere. Pull them out of the suitcase and pop them in the drawers and all of your sock stay in one place. Your underwear don't get mixed up with other items so you think you forgot to pack enough until you find them when you get home. I love mine.
