Armor of Auramycos

It is a dark, spongy fungus that acts as a liner on the inside of armor. It quickly wicks away perspiration keeping you cool when you are active and acts as insulation when it's cold. It confers a +1 to your armor class as it acts as a shock absorber. It also increases the comfort of your armor considerably, as it is thicker at pressure points and helps distribute weight. Because of this,  you can sleep in armor lined with the fungus without taking levels of exhaustion and allowing normal short and long rests.
