@idea from Snake
So, I'm watching Escape from L.A. and they give Snake (Yeah, I know). These clothes that Nullify heat detection. That would be cool.
We can combine the two, have clothes that nullify heat detection and make you invincible, call it the OMGWTF Suit.
Seriously though, this would only affect people who have thermo-goggles. Add this to spot #2713 on The List.
