I'm tough on organizational items, as they add weight, even as they organize. But these are light and make separating "worn once" clothes from "not yet worn" clothes easy. It helps me bring fewer things, and that lightens my packing, as well as organizes it.
Have used these on many trips. They help keep me organized e.g shirts in one, underwear in small, slacks and shorts in large. My Australian friend saw them and bought them. Excellent because you can see in the pack and zippers work easily.
The Ulralight packers were great on my last cruise. I only had one set and wished I had more. I will purchase more sets for my next trip. It made packing and unpacking the easiest ever!
I bought these bags after reading all the reviews here. I love the biggest size bag. I can organize my suitcase when I travel. Unlike other reviewers I find the biggest size the most useful for my needs. Since everyone prefers different sizes I would like to see LL Bean offer these bags individually or in different size configurations.
