Portable, concealed heat pad
I am one of the many guys who is forced to PE in secret. I am currently looking for another means of warming up in nothing but the security of a bathroom stall in a dorm. I don’t think a mug of water would work very well for this, so I am at least researching other means. The ideal device would be battery operated. It needs to generate a good about of heat and be renewable. Also, microwaves can’t be involved. It’s quite the challenge. Does anyone know of such a device?
I saw mention of battery operated hunter’s socks. Has anyone tried this, or experimented with similar devices?
