Soooooo soft and strong too!
This is my favorite hot water bottle so far. I've bought a few over the last few months and the quality of this one beats the other ones out.<br />The cover is soooooo soft, good quality material, and nice craftsmanship too.<br />The bottle has what looks like a nylon cap and threads. It's not metal, but this material will actually endure better than some of the "metals" I've seen in other bottles and it will definitely last longer than regular non-polyamide plastics. I left it in my chair and accidentally sat on it when I came back (full force - forgot it was there - I'm not what you would call light). It was fine, no leaks, no sound, it actually bounced me back up some. Now, I wouldn't recommend jumping on it or anything but if you're forgetful like me... =)
