The Callaway Big & Tall Opti-Dri Stretch shorts are top-performers that every golfer should have. The shorts feature fabric technology such as Opti-Dri, Opti-Shield and Opti-Stretch. Opti-Dri transfers moisture away from the body, keeping you dry and cool for all day comfort. Opti-Shield provides protection from the sun and Opti-Stretch ensures maximum range of motion by allowing the shorts to move when the player moves. The Big & Tall Opti-Dri Stretch shorts also feature an expandable waist band, 4 pockets and the Callaway chevron logo above the back right pocket.
