Hats, worn on the feet in most civilized societies, are a way of flaunting wealth that would've been confiscated after a [[DriveKill]].  Hats are bought at Deimos' Haberdashery ((though it really should be Deimos's))((but I thought it was supposed to be Deimoses?))((Deimoses'?))((Deimoses's?))((Des Moines?))((Del Taco?)).  1000 req will buy you a size 1 hat.  After that, each next sized hat costs 10% more than the last.  Thus the formula is log(cost / 1000) / log (1.1), rounded up.  You can upgrade a hat (though Deimos requires you to spend at least 10% the current value of your hat to do so).  This is where all that req should go before you kill the [[improbability_drive|Drive]].
