There is no difference between them other than style and color options.
(The RAPTOR bands cost a little more as they were designed by a well known design company who requires some compensation.)
WHAT’S MY SIZE?
The wristbands are made of surgical grade silicone and will stretch over your hand.
They do not need to fit either loose or tight for maximum effectiveness.
As a rule, 90% of men wear a 8” band and women a 7” band. The 9” are for very large wrists.
We have a quick and easy exchange policy if you do order the wrong size.
