In a drizzle, you will need rain gear that is pretty quiet to keep from being detected while you draw your bow or when walking to your stand. The deer where I hunt are skiddish so I have done some things to eliminate the sound of my rain gear, even though the light rain gear I own is very quiet. Put some fleece or something over your rain gear so when you draw it will be silent. The outer gear will get wet, yet the rain gear will protect everything beneath it from getting wet.

If you have to ramp up to heavy rain gear b/c it is pouring, it really will not matter how loud the dang stuff is because the sound of the rain will cover the noise. You can also put on another jacket over your heavy rain gear to reduce the noise.
