Simply put, seasoning is a treatment for hide (sheepskin, moose, cow, etc.) bagpipe bags to help them maintain their air-tightness. I've never played a hide bag, so I don't really know how many brands there are, but 'Airtight' is the most well known (for various reasons).

It's my understanding that most hide-playing pipers will treat the bag at least once a year. More often if they play frequently.

From what I've read, the general process is to remove the sticks and put stoppers in the stocks, heat up the recommended amount of the seasoning then pour it into the bag. The seasoning then gets massaged into the hide and all the seams, then any excess is drained out and the bag is hung up & left to dry out at least overnight.

Those more familiar with the process - having done it themselves - may correct me &/or elaborate as necessary.
