A sporting good implement, such as a hockey stick or ball bat, includes a main body. The main body may be formed from multiple layers of a structural material, such as a fiber-reinforced composite material. One or more microlattice structures may be positioned between layers of the structural material. One or more microlattice structures may additionally or alternatively be used to form the core of a sporting good implement, such as a hockey-stick blade. The microlattice structures improve the performance, strength, or feel of the sporting good implement.

A protective sports helmet that includes a chin strap system that allows for rapid, one-handed adjustment of a chin strap assembly by the player while he/she is wearing the helmet is provided. The chin strap assembly includes a protective chin cup and a pair of straps extending from opposed sides of the chin cup and having a plurality of securing elements. The assembly also includes a pair of adjustable connectors affixed to the helmet and that include a central opening that receives an extent of the strap and a lever that engages a portion of the securing elements. The adjustable connector allows movement of the strap in a first direction, and prevents movement of the strap in a second direction when the lever is engaged with at least one of the securing elements. The adjustable connector allows movement of the strap in both the first and second directions when the lever is not engaged with the securing elements.

A helmet is provided having one or more layers of foam forming a first helmet shell nested inside a second helmet shell. Left and right circular ear openings are positioned on opposing sides of the first helmet shell and on opposing sides of the second helmet shell. A faceguard is attached to the first and second ear opening at opposing sides of the second helmet shell and a right ear hole anchor and a left ear hole anchor, each have an inside surface and an outside surface. One each of the ear hole anchors attach to the first and second circular ear openings of the second helmet shell at their inside surface and a first end of the faceguard attaches to the outside surface of the right ear hole anchor and a second end of the faceguard attaches to the outside surface of the left ear hole anchor.

A protective helmet including an outer shell, and a liner assembly received in the outer shell and connected to the outer shell, the liner assembly defining a front portion configured to overlay a front of a head of a wearer, a rear portion configured to overlay a rear of the head of the wearer, a top portion disposed above and out of contact with a top of the head of the wearer when the helmet is worn, and two opposed side portions each configured to overlay a respective side of the head of the wearer. Each of the front, rear, side and top portions includes at least one zone where the liner assembly includes a plurality of overlapping layers.

A helmet features an inner shell, a non-rigid outer shell surrounding the inner shell in outwardly spaced relation therefrom, and a plurality of impact absorbing layers disposed between the shells. Each impact absorbing layer features an envelope, and a plurality of impact absorbing members disposed internally within said envelope. At least one adjacent pair of impact absorbing layers are displaceable relative to one another to enable impact-driven shifting between the adjacent pair, whereby impact energy is absorbed by the impact absorbing members within the impact absorbing layers, and absorbed and/or redirected by the impact-driven shifting between the adjacent absorbing layers. Resiliently stretchable material is attached to the adjacent layers at discrete locations such that, after being stretched by the relative shifting, the material returns to a relaxed state to reset the shifted layers back into a default positional relationship, in which ventilation passages in the absorbing layers are aligned.

A martial arts training device with scoring system, device comprising a padded device designed to be struck by a participant; and a scoring system attached to padded device, scoring system comprising: an impedance-based impact sensing mechanism that detects a source of impact comprising at least one impedance changing mechanism that changes impedance as each of conductive material is moved towards and away from impedance changing mechanism as the first participant delivers the impact; an impact sensing mechanism for which mechanically detects the force of impact creating electrical charges; at least one impedance-based impact measuring scoring system determining the source of the impact that occurred based on a change in impedance electromagnetically in said impedance changing mechanism; and at least one impedance changing rate determination engine configured to determine a rate at which the impedance changes in impedance changing mechanism; and at least one impact force determination engine configured to determine a magnitude of a force of the impact based on the rate at which the impedance changes in impedance changing mechanism and the impedance changing a rate data.
