A panel attachable to a backpack body. The panel having at least one through-hole formed therein to allow air to flow into a gap defined between the panel and the backpack body. An air-moving device is mountable to the panel, with an outer portion of the air-moving device extending forwardly from the panel and an inner portion of the air-moving device positioned in the gap. The air-moving device causes air to flow into the gap through the at least one through-hole and into one or more inlets of the inner portion. The air-moving device causes air to flow out one or more outlets of the outer portion.

Disclosed is an elastic hollow breathable massaging burden-reducing backpack. Two flexible straps are arranged on the front surface of the backpack in a bilateral symmetry manner, the upper end of each strap is connected to the upper part of the front surface of the backpack through an elastic rope, and the lower end of each strap is fixed by a strap buckle. Each strap is provided with an elastic auxiliary strap, two ends of which are fixed on the corresponding strap. Massage pads are arranged on the inner sides, in contact with human shoulders, of the straps, and a groove, corresponding to the human spine, is formed in the front surface of the backpack.

Articles are described herein. An example article may comprise a first surface comprising a first lattice. The example article may comprise a second surface at least partially spaced from the first surface. The second surface may comprise a second lattice. The first surface and the second surface may define a cavity therebetween. The first surface and the second surface may be formed as a unitary body. A configuration of the first interconnected struts, the second interconnect struts, and the third struts may be tunable to control a stiffness and ventilation of the example article.

Backpacks having lumbar pads as at least one component that has been manufactured using 3D printing or other additive anufacturing technologies. backpack may include 3D manufactured parts including a lumbar pad, shoulder harness, hip belt, or back panel. The component or lumbar pad may include a lattice structure that allows airflow or provides cushioning. The lattice structure may: have multiple layers, include a network of beams and nodes (e.g., that create cells), or be monolithic. The cells may be polygons (e.g., hexagonal) or cells may line up in multiple layers of lattice structure. Cells that line up may have equal numbers of sides. Other embodiments include systems for providing custom backpacks where consumers enter consumer body dimension(s) and the system fabricates a custom backpack or component using the body dimension or desired load capacity, for example, using 3D printing.

A backpack-type assembly may include: a body; and a base member. The body may include a cooling fan. The base member may include: a back plate attached to the body; and a harness attached to the back plate and configured to be worn on a user. The harness may include: a cooling port; and at least one shoulder belt configured to be worn on a shoulder of the user. The cooling fan may be configured to circulate cooling air into or out of the base member through the cooling port of the harness.

A lining for items of clothing, footwear and accessories, including a fabric with a plurality of channels which are alternated with ribs, the channels at least partly have a differentiated width.

The invention relates to a backpack (10) having a stowage space (18), which on its side facing the back of a user of the backpack is delimited by a back part (20). The backpack (10) includes a net element (12) and a frame arrangement (22), which for tensioning the net element (12) is designed in such a way that an intermediate space (24) is formed between the back part (20) and the net element (12) when the net element (12) is tensioned. The backpack (10) has two shoulder straps (14, 16) for carrying the backpack (10) on the user's back. The shoulder straps (14, 16) have end areas (42, 44) that cross the intermediate space (24) and are fastened to the back part (20).

A body-carried device includes a receiving bag, two carrying straps, and a heat dissipation system on the backside of the receiving bag. The heat dissipation system has a pump and an airflow guide tube unit. When a user's lower back directly contacts and pushes the pump, the air in the pump is pushed into the main tube and branch tube of the airflow guide tube unit. Some of the air exits the body-carried device through the main tube while the remainder of the air enters the heat dissipation area of the receiving bag through the branch tube. When the user's lower back moves away from the pump, the pump is elastically restored in shape to draw ambient air through the airflow guide tube unit into the pump.

An attachable backpack apparatus for reducing sweat and heat is described herein. The attachable backpack apparatus may comprise one or more of a body, a backpack attachment component, and/or other components. The backpack attachment component is configured to removably engage with carrying straps of a backpack a forming an as-used position of the attachable backpack apparatus. The as-used position of the attachable backpack apparatus causes the body to be disposed at or near a lower portion of the backpack. The attachable backpack apparatus may separate a portion of the backpack from a portion of the user's back. Contact between the backpack and the user is therein reduced, while maintaining the traditional strap-based engagement of the backpack to the user and without adversely modifying the backpack's structure. The separation may create a channel between the backpack and the user to allow air to pass through.
