1/4 ounce bottle of Water Proofing Powder.
Applied to your feathers after your arrow is fletched this non toxic, odor free and nearly weightless powder will help guide your feather fletchings in any weather.
Apply the powder by pouring it into a ziplock baggie.
Insert the fletched end of your arrow into the powder.
Shake the powder onto all of the fletchings and then pull each fletching back to ensure the powder gets between the feather barbules.
One bottle treats 12 arrows.
