Soft and fuzzy inside, thin layer of neoprene outside, lightweight and not a whole lot bigger than the device it's protecting ... unless you're going into a war zone, this is just the right amount of protection. Because it's stretchy, it grips the device inside, holding it in firmly, not so firmly that it's difficult to get out, but firmly enough that you can toss it across the room into your luggage, and expect it to stay put. I had one for my 3rd generation Kindle, for two years, before I gave it to a relative and bought a new Kindle. It's tough, it lasts, and does it's job. I've ordered one for my new Kindle, and one for my tablet which is the same size as the Kindle Fire.
