Grangers is heat activated. as long as you don't blast it with the heat of the inside of a McDonalds apple pie it wont shrink (much). if you don't have access to a tumble dryer and have an allergy to laundrettes you can iron your jacket after proofing which will activate the reproofing but I haven't found this nearly as affective as tumble drying in the past
