Im just pondering other avenues, and piggybacking onto the above question about providing heat, you could always sow a pouch of sorts into a shirt/jacket/sweater. The pouch could be largish and have a safe way of "sealing" it.
I sometimes carry mine around in my hoodie pouch. And it's nice and dark in there too.
Edit idea : or just sow half of a hoodie pouch shut.
