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 ball bat, extending along a longitudinal axis and configured for impacting a ball, may include a handle portion, an end cap, a barrel and a tubular insert. The barrel longitudinally extends along the longitudinal axis between the handle portion and the end cap. The barrel has a distal end and an inner surface, a portion of which proximate the distal end forms an insert mounting portion. The tubular insert may have a cantilevered portion having an outer surface separated from the inner surface. The cantilevered portion is cantilevered from the insert mounting portion independent of the end cap and forms a majority of a length of the tubular insert.

A method of making a ball bat may include forming a bat frame with a handle and an inner barrel structure, providing spacer elements extending radially outwardly from the inner barrel structure, and forming a barrel shell having a main barrel and a tapered section. An inner diameter in the tapered section may be equal to an outer diameter of a first one of the spacer elements. The method may include mechanically locking the barrel shell to the bat frame by passing the handle through the barrel shell and moving the barrel shell toward the inner barrel structure until the barrel shell contacts the first one of the spacer elements. A gap is maintained between an outer diameter of the inner barrel structure and the barrel shell. The barrel shell may deflect during a hit to create a trampoline effect, while the inner barrel structure limits the deflection.

A bat includes a handle configured to be held by a user having a first end and a second end opposite the first end, the first end includes a knob having a larger diameter than the handle. The bat further includes a barrel extending from the second end of a handle, the barrel configured to strike a ball during play. The barrel includes a first layer primarily composed of a single wall aluminum, a double wall aluminum, a single wall titanium, a double wall titanium, a single wall composite, or a multi wall composite. A second layer is connected to the first layer and configured to support the first layer to prevent the first layer from fatiguing, permanent damage, or exceeding applicable rules limiting the hotness of the bat.

A ball bat includes outer shell segments longitudinally spaced apart from each other to form a gap between them. A joint connects the segments. A first outer shell segment may include a barrel portion of the ball bat and at least part of a tapered portion of the ball bat. A second outer shell segment may include at least part of the tapered portion. The joint may include a tubular element having a first portion positioned within the first outer shell segment and at least partially overlapping an interior surface of the first outer shell segment, and a second portion positioned within the second outer shell segment and at least partially overlapping an interior surface of the second outer shell segment. The tubular element may include an elastomeric material. In some embodiments, the joint may be formed by an elastomeric material connecting the outer shell segments in the gap.
