Abstract
Embodiments herein may provide multi-layer structures for straps or utility packs. Embodiments include a multi-layer structure for support elements of a utility pack, such as straps (e.g., backpack straps, duffle bag straps, etc.) and/or panels (e.g., the back panel of a backpack). The multi-layer structure may have improved breathability while still retaining other desired properties, such as resilience, strength, comfort, padding/cushioning, and/or durability. Some embodiments of the multi-layer structure also may be thinner and/or lighter than conventional padded support structures. Various embodiments may provide utility pack straps including a reinforcing layer coupled to at least one of an inner structural layer and an outer structural layer. In some embodiments, the straps may include both the inner structural layer and the outer structural layer. The inner structural layer may contact the body of the user when the strap is in use, and may be designed to provide cushioning to the user. The reinforcing layer may provide strength and/or stability to the strap.
