Sizing
Find the fit that stays put.
ARC Band uses adjustable S/M and L/XL straps. Choose the size that stays secure without feeling overly tight.
Fit matters
Secure enough to read. Comfortable enough to forget.
Optical wearables work best with consistent skin contact. ARC should sit above the wrist bone, stay flat against the skin and feel snug without leaving painful pressure.
For smaller to medium wrists.
For medium to larger wrists.
Measure once
Use the wrist you will actually wear it on.
- 01
Wrap a soft measuring tape around the wrist where you intend to wear ARC.
- 02
Keep the tape comfortably snug without compressing the skin.
- 03
Compare the measurement with the final published size chart before ordering.
During daily wear
Keep the sensor flat against the skin and move ARC slightly higher on the wrist if wrist flexion causes gaps.
During training
A slightly firmer fit may reduce motion at the sensor during exercise, but the band should never feel painfully tight.
During sleep
Choose a position that stays comfortable through the night. Consistent wear matters more than overtightening the strap.
