While the SCOTT neck brace should sit on the front member, shoulder wings and thoracic member, as close to the body as possible, it can be worn over a jacket as long as it sits correctly on the shoulder, chest and the thoracic member areas. We cannot provide any assurances with respect to use of third party protective gear with the SCOTT neck brace since the manner in which such third party gear is used or worn, and its condition, may significantly affect the function of the brace.
