A leg sleeve with means for gripping used to aid in lifting a jumping player, especially for lineouts in Rugby Union. The simple, reuseable, easy to use leg sleeve provides a level of effectiveness, comfort, convenience, and safety not provided by conventional methods. Means for gripping include a thickened band or grip attached to a sleeve material. The means for gripping may be formed by attaching a semi-rigid material. The means for gripping may be formed by attaching extra layers in sections or in rolls. The means for gripping may be shaped to match the hand of a lifter. The means for gripping may comprise memory foam. The leg sleeve may further comprise a knee cutout or a hamstring cutout. To use, leg sleeves are applied to the legs of a jumper. When the jumper jumps, one or more lifters grip the leg sleeve. The lifters lift the jumper higher, support the jumper in the jump while the jumper attempts to intercept a ball, and safely lower the jumper.
