The mystery was fun, and the fabric lived up to the leak-proof promise on a light day. It's surprisingly breathable for something so protective, which I really appreciate.

I wasn’t sure what I’d get, but the fabric in each pair is noticeably soft and the leakproof layer held up perfectly during a long day out.

The fabric is surprisingly breathable for how well it holds up, and the waistband stays put without digging in. I wore one on a long travel day and felt totally secure. This kit took the guesswork out of finding the right fit.
