I needed a clear bag for a five-hour test I had to take.  We weren't allowed to have anything that wasn't in a clear container.

The bag was perfect to let me carry all of my supplies, including two frozen bottles of water.

Everything was easy to see, so the people who had to check everything had a very easy time of it.

Because it's clear I haven't figured out what else to use it for, but it was more than worth the price I paid for it for what it provided.
