I had my wife sew me up some tubes from camo material , just large enough in diameter to go over my briadheads.
About 6" long.
Waterproofed them
I slip them over the broadheads and up over the feathers.
Hold them in place with a Band Aid adhesive bandage wrapped around them and the
shaft, just before the fletching.
Keeps the feathers dry.
When I want to shoot, just pull it off, over the feathers and drop it.
