Optimal brace fitment is achieved by selecting the correct rear mount offset, and opting to use (or not use) the optional shoulder padding for height adjustment that suits your body and range-of-motion of your head/neck, as described in the Atlas Brace™ user manual.
While fitting a brace, there are 2 key steps to follow for length and height adjustment:
1 - While standing straight up, the brace should fit snug on your chest and back, and the shoulder padding should be resting on your body. If the shoulder padding does not rest flush on the body, there will be a gap between the shoulder padding and the body. This shows the brace is too tight on the chest and the rear mounts supplied on the brace should be reversed to change the offset, this will add length to the brace to create a better fit, allowing the shoulder padding to rest on the body as it should.
2 - Once the brace is properly fitted for your chest size, determine which height setting is right for your individual body type and neck length so that you will have proper range-of-motion before starting activity. Put on a helmet to determine which setting is right for you, and if you do not feel your range-of-motion is sufficient, remove the optional shoulder padding from your Atlas Brace™ by pulling down on the outer edge of the bottom shoulder pad. The padding will simply “pop” out of the top shoulder pad. Repeat for the opposite side. Make sure the brace still fits snug on the body, and the shoulder padding is resting on your shoulders.
