A neck brace has two legs with a gap between them and the legs extend on either side of the wearer's neck and along the front of his torso. Shoulder protuberances, and chest protuberances extending laterally from each leg, are received underneath the shoulder straps of a harness, in the region of the wearer's shoulders and chest, respectively. A recess is defined on an underside of each leg between the shoulder protuberance and the chest protuberance to form a beam that is elevated above the wearer's chest. Each leg and its associated chest protuberance, define a channel in which one of the shoulder straps of the harness is receivable to be held captive.
