That's illogical. If they can only exchange heat through their face and feet, covering up everything else has no effect. It's like if you want to test a bulletproof vest, so you shoot the thing hanging the vest. Well you didn't test the vest did you?
Or if we want a better analogy, it's like if you're intentionally trying to overheat the computer so you put heavy cloth everywhere except the air exchangers and heat sinks. Well you're blocking the heat very well are you?
You're a dingus who doesn't understand that they can only release heat through those small areas. They can still absorb and contain heat with the rest of their body.
Imagine if you could only sweat through your face. If you were naked, you'd be cool. If you were wrapped in a fur coat and plastic wrap, you'd be much warmer, with the same limited amount of heat release.
