It is common practice to cover the transmitters on lavalier (sic) 
microphones to prevent talent (especially in musical theater) from 
sweating all over the electronics.

from http://harada-sound.com/sound/handbook/rfmics.html (I never used the 
absorbent material trick, but it makes sense)

Avoid placing the transmitter directly against the performer's skin 
without a barrier to prevent moisture from entering the transmitter and 
damaging the fragile electronics. Most engineers use unlubricated condoms 
in which to stuff the transmitter before rigging the transmitter to a 
performer. Normal-sized condoms work just fine- stretch them out a bit 
before rolling them onto the transmitter. Other people use small sandwich 
bags in a similar fashion. At the top of the transmitter, where the 
connectors and switches are usually located, stuff the top of the 
bag/condom with cotton or other absorbent material, then tape the whole 
package shut, allowing only for the antenna and microphone wire to stick 
out. Some engineers use art-gum eraser to mold around the antenna and 
microphone connectors, providing a watertight seal around those sensitive 
areas. Taping down all switches on a transmitter before the transmitter is 
applied to the performer is also a good idea to prevent inadvertent or 
intentional problems.
