A thigh protector for rodman comprised of a shield member which extends over the thigh from the groin to approximately the knee and a reinforcing member positioned underneath the shield member at a location where the rodman will position one or more rods. The reinforcing member is preferably comprised of a narrow piece of curved material that serves the function of keeping the shield member centered on the front of the rodman's thigh and also distributes the weight of the one or more rebars that are positioned on the rodman's thigh so as to reduce the likelihood of the one or more rebars injuring the rodman's thigh. In use, the rodman carries the bundle of rebar on their shoulders and then positions a front leg forward with the knees slightly bent so that the thigh, which is wearing the thigh protector, is at least partially horizontal. The bundle of rods are then dropped onto the thigh and the rodman holds them in place with at least one of their hands. A single rod is then selected out of the bundle of rods and is dropped so as to slide down the shield member towards the rodman's knee from where it falls to the ground. The shield member protects the thigh and the rodman's clothing from damage that results from the rebar sliding along the shield member and the reinforcing member further protects the thigh from injury as a result of the thigh having to bear the weight of the bundle of rods.
