I purchased this with the sole intent of using it to store 2 days worth of outfits in my carry on bag, on the off chance my suitcase were to be separated from me for a period of time.

It worked very well at reducing some of the space the clothes took up. Not much, but then I didn't put too much into it in the first place. It could've fit more than I put in. I did appreciate the rigid-ish shape, as it helped to organize my carry on very well.

Used it a few times since June and have had no problems. We'll see how long it holds up, but it's doing great so far, Would definitely recommend.
