A wearable container or pack that is quickly convertible into front and rear body armor without removing the pack from the torso of the wearer. The container or pack may include a bag that may be easily separated from the container or pack, and quickly dropped from the container or pack, providing supplies for another person.

An eyewear lens coupling system and methods can be used during assembly of an eyewear. The system and methods may advantageously decrease optical distortion of the lens during assembly and use and/or may also advantageously increase retention of the lens to the eyewear frame to improve the overall quality of the eyewear.

Energy distribution structures provide architectural flexibility in various configurations, materials, and scalability, which enables a vast number of applications. An energy distribution structure or array thereof may include a three-dimensional outer component and a three-dimensional inner component within the outer component. The outer component absorbs and redirects initial energy from an applied energy event, and the inner component absorbs and redirects residual energy from the applied energy event. Such an applied energy event may be caused by a ballistic or non-ballistic impact, an instantaneous or prolonged impact such as atmospheric pressure or decompression, explosive overpressure (shockwave), low-velocity contact, and blunt force trauma. Energy distribution structures can increase the strength, resilience or survivability of such events, and reduce the injury or damage to target objects such as people, vehicles, structures, vessels and surfaces by shielding same from such events.

A load carrying and force distributing device to be worn on a user's limb is described. The device has one or more support members and a plurality of elongated compression members that couple with each of the support members at locations that are circumferentially spaced around the user's limb. The space between the plurality of compression members provides a relief area. The load carrying and force distributing device compresses the soft tissue of the limb against the bone structure to thereby reduce motion of the bone structure towards a wall of the load carrying and force distributing device when worn on the limb. A method of fitting a load carrying and force distributing device to a limb is also described. The method includes coupling the elongated compression members to each of the support members and adjusting compression to thereby reduce motion of the bone towards a wall of the device.

There is provided a protective glove to cover at least a portion of a hand of an archer during the shooting of arrows from a bow, which glove is designed to resist a broken arrow from puncturing through the glove and entering the flesh of the user. In particular, there may be a palm section, made of a first arrow puncturable material that covers the palm of the users hand. There may also be a protective section, located on the glove covering the back of the hand of the user, made of a second material that has a high weight-to-strength value, coupled to the palm section and positioned so that a broken arrow being shot from a bow will have a higher likely hood of hitting the protective section than hitting areas not having the protective section.
