Lab coats are really cool though.
I mean thermally.
They're white, and white tends to reflect heat. And they're not that heavy either. They're meant to prevent chemical spills getting on clothing, rather than insulation.
@Tezcatlipoca : They're small though. Bigger is better, though I don't tend to rate it as important as glasses nor thighs.
@Tezcatlipoca : How about this then? Bigger is more functional from an external standpoint (purely external, mind you), and I can't see any reason why increased functionality wouldn't be regarded as improvement.
