Why is there a bottom button?
 

If we are never supposed to use it?

Is it like a spare tire?

�� what do you mean ‘bottom’ button?

I see one on forum at the bottom labelled ‘top’ ... is that related?

I'm being a bit of a troll. Here's why...

Oh rite.

I do my buttons upside down.

Maybe if it's really cold and we need a tiny bit more warmth we are allowed?

I was told not to use all the buttons on a suit and it made me upset why have them then why!?
