I have seen a lot of guys building Rube Goldberg contraptions to air out their armor after a mission. I recently ran across Russ Innovations’ design. They offer a hanger designed to not only dry the vest between uses but provides a handy way to store it or configure it for use.
The hanger on the right is slightly larger and designed for full military armor.
As you can see from the side view, the design allows for ample air circulation and the hanger can be hung up or opened like an easel.
The price is reasonable and it is warrantied for 25 years from the date of purchase. Available from Flakvesthangers.com.
