A protective case for large objects including a lock housing formed from a first section and a second section, both of the sections including at least one external subsection and at least one internal subsection configured to telescope inside the external subsection; and an extension lock comprising a lock housing and a compression lock, the lock housing including a screw-threaded channel, and the compression comprising at least one screw-threaded shaft with a compressive component on the interior end and a lock handle on the exterior end, the screw-threaded shaft configured to matingly engage with the screw-threaded channel of the lock housing; the compression lock configured to descend in the lock housing and compressingly lock the internal subsection in an extended position upon locking rotation of the compression lock; and the compression lock configure to ascend in the lock housing upon unlocking rotation of the cam latch.

Case for containing an item and method of manufacture comprising: a first panel having a perimeter edge and at least one hinge for folding the first panel. A second panel having a perimeter edge and at least one hinge for folding the second panel. A side panel. A first fastener configured to attach the side panel to the perimeter edge of the first panel. A second fastener configured to attach the side panel to the perimeter edge of the second panel. Method of manufacture of a layered material comprising the steps of: placing a substrate between a first and a second layer of self-reinforced polypropylene (srPP). Bonding the layers of srPP and substrate by: stitching, or riveting through the first layer of srPP, the substrate and the second layer of srPP; or gluing the first layer of srPP, the substrate and the second layer of srPP together.

A device for carrying a surfboard, similar sporting equipment or other objects. One embodiment is comprised of webbing material with one or two primary loop(s) having a loop buckle that slides along the primary loop and a strap element that in combination with the loop buckle creates a secondary adjustable secondary loop. The secondary adjustable secondary loop is used to hold a surfboard or other object securely in place via gravity acting on the object being carried and the primary loop, or adjustable primary loop supports the surfboard from one or both of the user's shoulder allowing hands free operation. When not utilized as a carrier the device can be worn, such as a belt. The user keeps the primary loop compressed together, wraps the carrier around his/her waist, through the loop buckle and then attaches it back onto itself. A personal flotation device can be attached to the strap element so that carrier and personal flotation device from a single unit.
