If you have a Bannatyne bag, it seals in ALL the moisture from your breath. This will eventually wreak havoc with your drones, and worse yet, cause wooden pipes to crack and split. Do NOT try to cut corners by rationalizing that you are a ‘dry blower’, there is no such thing with a Bannatyne bag. This Kanister system is worth every penny, both for protecting your pipes, and for making your playing sessions more enjoyable.
