Various systems and methods relate to an adaptive chair system having (i) a stowed mode in which members of the chair frame are compactly contained within a multi-function bag (MFB), and (ii) a deployed mode in which the multi-purpose chair is configured to transition between at least two seating modes. In an illustrative example, the chair may be provided with an adaptive frame which may be reconfigured to transition between the seating modes. For example, the chair may transition between any of a vertical/upright (chair) mode (e.g., FIG. 8B), a vertical/upright (chair) mode using trek pole handle segment(s) (e.g., FIG. 1C), a low-profile/recon (seat) mode (e.g., FIG. 2B), and a longitudinal/lounge mode (e.g., FIG. 2B). Various embodiments may advantageously provide an adaptive chair system in an ultralight form factor which may fulfill multiple functions including, by way of example and not limitation, seating, sun/rain canopy, footrest, or some combination thereof.

A convertible backpack that can be used as an edge protection mat to protect ropes against abrasion and includes a flexible mat or sheet that can be configured into a pack and carried on the back of a user to carry equipment, clothing, or other gear.

A survival backpack system includes a main bag, and a pair of shoulder straps for mounting the main bag on a user's shoulders. The system includes a plurality of gear packs, all the same size, and each containing a different type of survival gear. The main bag forms a plurality of gear compartments, each slightly larger than each of the plurality of gear packs, each of the plurality of gear compartments being accessible through an opening in the top panel. A hydration compartment is accessible through an opening in the bottom panel, the hydration compartment being sized and shaped to receive a hydration pack therein.

A modular backpack system includes a personal floatation harness having an automatic inflator mechanism and pack attachment features; and a plurality of pack modules selectively attachable to the pack attachment features to form a floatation-enhanced backpack. Each one of the plurality of pack modules may further include a different arrangement for accommodating accessories. For example, the different arrangements may include arrangements having different compartments. Other arrangements may have different attachment features. The different attachment features may include different lash points. The backpack module may be one taken from the list of: a pack adapted for kayaking with a waterproof compartment and lash points for ready access to accessories; a pack adapted for sailing with waterproof and non-waterproof compartments; a pack adapted for hiking with multiple compartments for tools and supplies; and a pack adapted for everyday carry (EDC) having multiple quick-access compartments for carrying everyday tools.

A rigid piece of luggage with a pair of removable, telescoping posts which suspend a clothing rack above the luggage. This allows the user to place wardrobe changes in an organized and ready-to-wear orientation for dance competitions, plays, or other events where the user needs quick access to clothing. This could also be used for regular travel for hanging clothes directly from the user's luggage. The telescoping pole has a base which snaps into receivers within the luggage and which then can be telescoped upward to suspend the clothing rack. A cover can seal the receiver when not in use. A button can be depressed to release the telescoping arms, or the spring element could include that functionality itself. A curtain could be used with the clothing rack for privacy on-the-go.
