Great product, well made. The zippers are quality and seem like they'll last for a long time. I'm adding to my review that I just took a month long vacation with my daughter out west. We packed (shared) one large suitcase and used these packing cubes to distinguish our clothing. I used the green and she had pink ones from another manufacturer. They both worked well allowing enough mesh to allow us to see our clothes. Pants-shorts for one, shirts for another, underwear, bras, socks for the smaller size and so on. The best was when we were too tired to haul in the large suitcase, these packs were easy to grab a couple for the night for a quicker start the next day. I also ordered shoe bags with clear toes (to see which pair of shoes) and loved them. They were much easier and more helpful than using grocery bags.
