Hard of Hearing in the OR

Unusual problem.  I have to cover my hair at work.  The caps I usually wear come down over or on my ears.  I've tried it a few different ways.  Today, I went with a skull cap but the thing was rubbing on the HA and sounding like crinkling cellophane in my ear all day.    Hmmm.   Maybe a fabric hat will work better.  Give me the clearance for the mics and still keep my hair under control
