The invention is directed toward a trial golf club head and method for determining the optimal loft angle for any golf club, and in particular a hybrid-type golf club. The invention includes a trial golf club head having a face portion, a leading edge portion, a toe portion, a heel portion, a back portion having a trailing edge portion, and a sole portion. The sole portion contains a number of equally spaced graduated indicia, which are substantially parallel to one another and extend from the toe portion to the heel portion. The distance between the graduated indicia is approximately 3.75 centimeters (cm), which corresponds to an incremental loft angle of approximately 3 degrees. The sole portion has a radius of curvature of 71.67 mm, which extends from the leading edge of the face portion to the trailing edge of the back portion.

Recessed back portion of a golf iron

A golf club head comprising of a front plate integral with a primary body having a top, a sole, a rear portion, and a general periphery wherein the primary body and the front plate define a hollow interior and where the rear portion carries a weighting element that protrudes behind the general periphery.

Back design for a golf club iron head

An iron golf club and a set of iron golf clubs that have a variable weight distribution. Each iron golf club head has a cavity and a raised wall portion that extends upward from the sole and offset from the cavity. The raised wall portion is separated from the cavity by a groove set at an oblique angle to the face portion of the iron golf club The groove deepens the center of mass depth and lengthens the effective face length of the iron golf club. The width of the groove may vary between each golf club in a set of iron golf clubs, such that the width of the groove of the long irons is greater that the width of the groove of the middle irons, and the width of the groove of the middle irons is greater than the width of the groove of the short irons.

A form-fitting chest protector. In one embodiment, the chest protector includes a pair of detachably secured wing portions. A main portion of the chest protector has a variable thickness and substantially overlies the chest and abdomen of the athlete to absorb impacts to the athlete from a projectile. The wing portions are separate from the main portion, but are detachably secured to the chest protector to permit each wing portion to be adjustable when the chest protector is worn by the athlete. The wing portions facilitate a constant form-fit no matter how the body of the athlete flexes.

A trial golf club and golf fitting system for determining at least one custom fitted golf club. The trial club includes a golf club head having a sole defined by a radius of curvature. The sole of the golf club head includes graduated indicia for identifying an optimal lie angle for the fitted club. When the golfer swings the trial golf club, the optimal lie angle of the fitted club is identified by locating the point of impact on the sole of the head of the trial golf club.

A protective leg guard having a removable insert for orienting the leg guard on a leg. The protective leg guard includes a protective knee portion having an inner surface generally contoured to substantially overlay the knee. A removable insert is adapted to fit between the knee portion of the leg guard and the knee when the leg guard is worn. The removable insert may be placed in a plurality positions on the inner surface of the knee portion and cooperates with the knee to maintain the leg guard in alignment on the front of the leg.
