SIZING
The pieces in our Rough Trade Gear leather and neoprene lines are available in a variety of sizes. Here are some of the standard sizes for reference:
To get circumference, take a string and slip it behind balls and over cock (where it meets your body). Mark string and measure the distance from one end to the other. Take that measurement and divide it by pi (3.14) to get the diameter for the ring size.
Tip: Measure a few times to ensure the correct size. String should be snug, but not too tight. When measuring for an inflexible material ring, do not go down a size!
Circumference: 5.5" = Diameter (ring size): 1.75"
Circumference: 5.75" = Diameter (ring size): 1.83"
Circumference: 6.00" = Diameter (ring size): 1.91"
Circumference: 6.25" = Diameter (ring size): 2"
Circumference: 7" = Diameter (ring size): 2.25"
