These dessicant powders are usually a combination of silica gel, and silica
powder. There are a lot of them on the market. They all work for drying
flies. The types with silica powder are somewhat better, as the powder also
acts as a floatant.

I use ground ( coffee grinder) silica gel to dry flies, and then a floatant
to waterproof them again. Works great, and the silica gel costs nothing. I
have about 40 pounds of it, collected from electronics packaging.
