The physics behind PowerCuffs can get super confusing (science), so here it is simplified*
**The more tiers (coils) and the thicker the gauge (the large size of copper we use) the more powerful the properties of the cuffs.

To make arm cuffs more standardized, we've shifted to XS-XL sizing. To be 100% sure of which size is best for you - please feel free to measure your arms.
To properly measure your arms for cuffs, please measure the thickest part of your arm (or where you would like your cuffs to sit) + your elbow and hand, to be sure cuffs will properly slide up your arm.
XS= 9- 9.5" | S= 10- 10.5"| M= 11- 11.5" | L= 12- 12.5" | XL= 13- 13.5"
If you don’t see your exact arm size, please round up to the nearest # or contact us. Measurements are based in inches.
PowerCuffs are slightly adjustable, however be sure to measure your arms as accurately as possible.
