I'm guessing junk. Maybe it just delaminates after a week. If you can't find anything about the brand through google, I'd assume the worst. That's been my experience with going through the similar "cheap or expensive" deal many times. Fwiw, I use an Exped Downmat which I love. It proved defective after a year, but they replaced it free of charge. Of course, if you don't have the $$$ for something like that, you don't have much choice - get the cheapie, and practice repairing punctures
