Abstract: A first lacrosse head constructed from a first material having first properties or a second lacrosse head constructed from a second material having second properties is selectively used in lacrosse activities, based on environmental conditions, such as temperature, humidity and/or solar activity, to provide generally consistent head performance as perceived by a lacrosse player across a range of environmental conditions. The first and second heads can be identical in structure, but constructed from different materials. For example, the first head can include a polyamide, optionally, Nylon 6,6 polyamide, and the second head can include a high performance polyamide resin, optionally a polypthalamide. An environmental indicator that provides visual and/or audible output with regard to environmental conditions can be included with at least one of the first head, the second head and a shaft to which the heads can be joined. Related methods of use are also provided.

Abstract: A lacrosse head including a spine element that is at least partially embedded or encapsulated in a base and sidewalls of the lacrosse head. The spine element can terminate short of a scoop of the lacrosse head. Where the lacrosse sidewalls are of an open frame construction and include a non-string hole, the spine element can define a spine element hole that is aligned with the non-string hole. The spine element can also include a transverse element that spans from an upper rail to a lower rail of the sidewalls adjacent a cross member of the sidewalls. The base and sidewalls can include viewing apertures through which some of the spine element can be viewed, while other parts of the spine element remain concealed. The spine element can be constructed from one plastic, while the remainder of the head can be constructed from a different plastic.

Abstract: A lacrosse head includes a ball stop (throat), a pair of opposing sidewalls, and a scoop. The sidewalls can include visible markings, or sets of indicia, on the front and/or on the rear of the head. The indicia can be located at 1.25, 3.0, and 5.0 inches from the ball stop. The indicia can be marked on the surface of the sidewalls, and/or can be in the form or protrusions on or recesses defined by the sidewalls. The indicia can provide consistent measurement locations to assist officials and others in measuring the lacrosse head to ensure that it complies with the proposed 2010 NCAA Men's Lacrosse Rules regarding the dimensional measurements for a lacrosse head. A method for molding the lacrosse head including the indicia is also provided.

Abstract: A reinforced lacrosse head having improved strength can include the following frame elements: a pair of opposing sidewalls each having a top end and a bottom end, a scoop extending between the sidewalls, a base extending between the bottom ends of the sidewalls, and a throat extending from the base for attachment to a lacrosse handle. The head can include at least one reinforcement member that is located at least partially in a frame element. The frame element can be constructed from two or more parts that are sonic welded or hot plate welded together around at least a portion of the reinforcement member. Methods of sonic welding or hot plate welding components of a reinforced frame element also are provided.

Abstract: A lacrosse head includes a ball stop having a bottom and side regions that transition at transition regions to head sidewalls, which are joined with a scoop of the head. The ball stop can include a longitudinal axis that extends toward the scoop. The transition regions can be located on a horizontal axis generally perpendicular to the longitudinal axis. At a distance less than or equal to 1.25 inches from the bottom along the longitudinal axis, opposing side regions and/or sidewalls are separated by a minimum width of 3 inches from the bottom. This construction provides a generally v-shaped ball stop that complies with proposed 2010 NCAA Lacrosse Rules regarding the dimensional requirements for a lacrosse head, while providing improved ball retention within the lacrosse head.

Abstract: A lacrosse head in which one of the opposing sidewall portions is shortened by bringing its lower rim upward relative to the corresponding lower rim of the opposing sidewall. At the same time, the upper rim of each of the opposing sidewalls is maintained at the same level. This moves the pivot point of the shortened sidewall closer to the player's hands and allows faster clamping when facing-off. Faster clamping likely results in an increased number of “wins”, or possessions, that occur after the face-off.

Abstract: A lacrosse head including a sidewall having at least one upper rail, extending between a base and a scoop, including a primary rail and a secondary rail. The secondary rail can diverge from the primary rail at a junction as the primary rail extends from the scoop toward the base. The primary and secondary rails can define an aperture therebetween, where the aperture accentuates the offset configuration of the head. The bifurcated upper rail can also enhance the strength of the sidewall at or near the base.
