The ProPosture Headband and comes with a 30-day money back guarantee and a 180 day construction defects guarantee.
The four-inch elastic headband with a hook and loop closure system allows one size to fit all people.
The ProPosture Headband comes with either four or six pounds of weight in ½ pound metal bars. This allows the user to start off with just one or two pounds of weight and build-up to more weight as their neck musculature strengthens.
It is important that the user does not start off with too much weight as this will cause the head and neck to fail and fall into the weight, rather than retract to a more normal posture.
Most females, children and smaller frame men are fine with the four pound unit. Larger frame males or females should purchase the six pound unit.
