In an embodiment of the invention, the outer skin is made of a material that is more energy absorbing than the material of the skeletal member. Corresponding methods for making the lacrosse head are also disclosed. ## Claims ### Claim 1 A lacrosse head comprising: a skeletal member formed in a closed loop, the skeletal member comprising a first sidewall portion, a second sidewall portion, a juncture portion joining the first and second sidewall portions, and a scoop portion joining the first and second sidewall portions opposite the juncture portion, the skeletal member being continuous from the juncture portion, through the first sidewall portion, through the scoop portion, through the second sidewall portion, and back to the juncture portion, the junction portion forming a juncture of the head adapted to receive a shaft; and an outer skin applied over the skeletal member, the skeletal member and the outer skin together forming a stop member adjacent to the juncture, two sidewalls, and a scoop connected to the two sidewalls opposite the stop member, the outer skin encapsulating at least a portion of the skeletal member along the two sidewalls, the skeletal member having a cross-sectional area less than approximately half of a cross-sectional area of the outer skin at a cross-section taken along a sidewall of the lacrosse head, the outer skin made of a first material and the skeletal member made of a second material, the first material having a durometer hardness lower than that of the second material, the juncture portion defining an opening in which to receive a shaft, the juncture portion being comprising a continuous ring around the opening such that the juncture portion encloses a shaft placed in the opening, and the juncture portion of the skeletal member providing the lacrosse head with structural support necessary to connect the lacrosse head to the shaft. ### Claim 2 (depends on 1) The lacrosse head of claim 1, the second material being more compressible and elastic than the first material. ### Claim 3 (depends on 1) The lacrosse head of claim 1, the skeletal member being solid. ### Claim 4 (depends on 1) The lacrosse head of claim 1, the head deflecting a maximum of about 0.5-1.2 inches in response to an approximately 60-pound force applied to the head in a direction parallel to a longitudinal axis of a shaft connected to the head. ### Claim 5 (depends on 1) The lacrosse head of claim 1, the outer skin applied to the skeletal member by one of insert molding, reaction injection molding, spray application, rotational molding, dual extrusion, and casting. ### Claim 6 (depends on 5) The lacrosse head of claim 5, the outer skin further joined to the skeletal member by an interference fit. ### Claim 7 (depends on 6) The lacrosse head of claim 6, the interference fit comprising cooperatively shaped dovetail components in the skeletal member and the outer skin. ### Claim 8 (depends on 1) The lacrosse head of claim 1, the outer skin defining an opening adapted to receive pocket threading. ### Claim 9 (depends on 1) The lacrosse head of claim 1, the outer skin defining a tab adapted to receive pocket threading. ### Claim 10 (depends on 9) The lacrosse head of claim 9, the tab being hook-shaped. ### Claim 11 (depends on 1) The lacrosse head of claim 1, the skeletal member and the outer skin defining an opening adapted to receive pocket threading. ### Claim 12 (depends on 1) The lacrosse head of claim 1, the outer skin defining openings adapted to receive pocket threading, and the outer skin being at least one of elastic, resilient, and shock absorbing. ### Claim 13 (depends on 1) The lacrosse head of claim 1, the lacrosse head having a back side adapted to receive a pocket and a front side opposite the back side, and the skeletal member being disposed in the two sidewalls within the outer skin nearer the front side than the back side. ### Claim 14 (depends on 13) The lacrosse head of claim 13, the skeletal member having a strut that extends toward the back side. ### Claim 15 (depends on 1) The lacrosse head of claim 1, the lacrosse head having a back side adapted to receive a pocket and a front side opposite the back side, and the skeletal member being disposed in the two sidewalls within the outer skin nearer the back side than the front side. ### Claim 16 (depends on 1) The lacrosse head of claim 1, the first material of the outer skin divided into separate portions, each of the separate portions comprising a different material, each of the different materials having a durometer hardness lower than that of the second material. ### Claim 17 (depends on 16) The lacrosse head of claim 16, a first portion of the outer skin encapsulating the skeletal member at the stop member, a second portion of the outer skin encapsulating the skeletal member at the two sidewalls, and a third portion of the outer skin encapsulating the skeletal member at the scoop, and the first portion, the second portion, and the third portion each made of a material having a durometer hardness different from the materials of the other two portions. ### Claim 18 (depends on 16) The lacrosse head of claim 16, a first portion of the outer skin comprising the stop member and the two sidewalls, and a second portion of the outer skin comprising the scoop. ### Claim 19 (depends on 1) The lacrosse head of claim 1, the skeletal member comprising one of nylon, polypropylene, polyethylene, amorphous polar plastics, polymethylmethacrylate, polystyrene, high impact polystyrene, polyphenylene oxide, glycol modified polyethylene terphthalate, acrylonitrile butadiene styrene, semicrystalline polar plastics, polyamide, urethane, polyketone, polybutylene terephalate, acetals, acrylic, acrylic-styrene-acrylonitrile, metallocene ethylene-propylene-diene terpolymer, spring steel, and fiber reinforced composites. ### Claim 20 (depends on 1) The lacrosse head of claim 1, the outer skin comprising one of nylon, urethane, sanoprene, polycarbonate, partially crosslinked halogenated polyolefin alloy, styrene-butadiene-styrene, styrene-ethylene-butylene styrene, thermoplastic olefinic, thermoplastic vulcanizate, ethylene-propylene rubber, polyvinyl chloride, polyethylene, polypropylene, and acrylonitrile butadiene styrene. ### Claim 21 (depends on 1) The lacrosse head of claim 1, the outer skin encapsulating the skeletal member along the scoop. ### Claim 22 (depends on 1) The lacrosse head of claim 1, further comprising a shaft disposed in the juncture, the juncture portion of the skeletal member being directly connected to the shaft. ### Claim 23 (depends on 1) The lacrosse head of claim 1, the juncture portion comprising a socket that fully encloses an end portion of the shaft, the juncture portion being disposed radially between the outer skin and the shaft thereby separating the outer skin from the shaft. ### Claim 24 (depends on 23) The lacrosse head of claim 23, the opening comprising a cylindrical opening.
