Please use a measuring tape and wrap it around your arm, thigh or stomach while you are wearing the pod or CGM. Pull the tape snugly and enter that measurement in inches into the custom size text box under the chosen arm band pattern.
I will sew the band to the custom size that is given.
If the band is too small or large, please email me at email@example.com. I will give a full refund if you contact me within 30 days.
