The packing pods were an add on expense for me. I came to the site to buy the neck pillow that my fiancé liked. The packing pods are made from really sturdy material, are light weight, and great travel accessories. It really helped me to stay organized on my trip to Australia, keeping things modular as I switched between bags for the airport or for local day trips. The large bag also came with a padded strap that made it super handy as a low maintenance beach bag/day bag for activities. It also worked a charm as a personal item to easily pack out some small but heavier items when we went over our baggage weight limit at the airport last minute. There are other cool things you can do with them too like loop the end and hang it on a rod in a hotel room. The three sizes are convenient for different kinds of things, but helps to keep stuff organized while traveling. Would recommend these packing pods! Was a great purchase! Thank you
