Measurement Instructions:

This spike mask is designed for a snug fit. We will add 2mm of clearance to your measurement, but 0.8mm of that is taken up by compressible foam. We strongly recommend using calipers to measure the diameter of the frontmost outer lip of your dew shield. If you do not have calipers, you might be able to get away with measuring the circumference using a fabric tape measure and dividing by π. But a cheap pair of calipers is a great tool to have in this hobby.
