Various articles of apparel having a cylindrical portion, such as an arm region or a leg region, for extending around a joint (such as an elbow or a knee) of a wearer are disclosed. The cylindrical portion includes a textile material, for example, and a pattern located on a surface of the textile material or knitted into the textile material. The pattern has a first density in at least one area of the cylindrical portion oriented substantially parallel to a plane of bending of the joint, and the pattern has a second density in at least one area of the cylindrical portion oriented substantially perpendicular to the plane of bending of the joint. A purpose of the pattern may be to decrease the probability of an overuse syndrome or other injury occurring as a result of use of the joint.
