A training device and method for baseball, softball, and other sports provides a plurality of fixed or adjustable bump elements on a transportable support surface so the device can be easily stored, transported, and positioned for hop drills and other training routines. In one embodiment, the device is a flexible one-piece mat or other support surface with a plurality of integral bump elements. The mat may be rolled for storage, transported with a carry arm strap, unrolled into a desired position on a field or indoor practice area, and then used to deflect balls that are rolled over it. After use, the device rolls up easily for transport and storage.

Disclosed is a system for a combination bag, mat, and flotation device. The system includes an elongated mat having an external surface, internal surface, a mat section first side and second side, and a mat section first side and second side. A pair of flotation devices are attached to the mat section first side and second side. Each flotation device has an internal air compartment, inflation nozzle, and attachment element, and when inflated, allow the mat to be used as a flotation device. A first fastener being in attachment proximate to the mat section first side and a second fastener being in attachment proximate to the mat section second side. The first fastener and second fastener are configured to removably mate with each other. When the mat is folded so that the first fastener and second fastener are mated and the zipper is sealed, the mat forms a bag configuration.

Various systems and methods relate to an adaptive chair system having (i) a stowed mode in which the members of the chair frame are contained within a compact flexible multi-function bag (MFB), and (ii) a deployed mode in which the MFB is adapted to releasably couple to an arm of the chair to provide a multipurpose accessory chamber. In an illustrative example, the MFB may, for example, fold in on itself in an accessory mode. The MFB may provide various utilities for hikers, for example, by providing a case to receive an inflatable bladder so as to form a pillow. The MFB may receive a thermal liner adapted to maintain, for example, food or beverage temperature. Various embodiments may advantageously provide a rugged, water resistant MFB system in an ultralight form factor that serves as a multipurpose accessory (e.g., to store items), yet provides a compact, adaptive chair frame containment.

A device for carrying a surfboard, similar sporting equipment or other objects. One embodiment is comprised of webbing material with fixed loop 24 having a buckle 22 that slides along the fixed loop 24 and a strap element 20 that in combination with the buckle 22 creates a secondary adjustable loop. The secondary adjustable loop is used to hold a surfboard or other object securely in place and the fixed loop 24 supports the surfboard from one 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 fixed loop 24 compressed together, wraps the carrier around his/her waist, through the buckle 22 and then attaches it back onto itself.

Disclosed is a system for a combination bag, mat, and flotation device. The system includes a rectangular elongated mat having an external surface, internal surface, a mat section first side and second side, and a mat section first side and second side. A pair of flotation devices are attached to the mat section first side and second side. Each flotation device has an internal air compartment, inflation nozzle, and attachment element, and when inflated, allow the mat to be used as a flotation device. A zipper is disposed on the perimeter of the mat. A first fastener in attachment proximate to the mat section first side and a second fastener in attachment proximate to the mat section second side. The first fastener and second fastener are configured to removably mate with each other. When the mat is folded so that the first fastener and second fastener are mated and the zipper is sealed, the mat forms a bag configuration.

Disclosed is a bicycle bag suitable to be straddled over a structural tube of a bicycle in a folded position and convertible to a backpack in an open position. The structural tube may include the top-tube or the bottom-tube of the bicycle. There is provided, in accordance with an embodiment of the present invention, a bicycle bag suitable to be straddled over a structural tube of a bicycle in a folded position and convertible to a backpack in an open position.

A device for carrying a surfboard, similar sporting equipment or other objects. One embodiment is comprised of webbing material with fixed loop having a loop buckle that slides along the fixed loop and a strap element that in combination with the loop buckle creates a secondary adjustable loop. The secondary adjustable loop is used to hold a surfboard or other object securely in place and the fixed loop supports the surfboard from one 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 fixed 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 the carrier and personal flotation device form a single unit.
