The modular backpack and harness system is a modular backpack. The modular backpack and harness system is interchangeable such that the modular backpack and harness system can be adjusted to the cargo being carried by the modular backpack and harness system. The modular backpack and harness system incorporates a harness structure and a plurality of cargo structures. Each cargo structure selected from the plurality of cargo structures removably attaches to the harness structure. The plurality of cargo structures are interchangeable. The difference between any first cargo structure selected from the plurality of cargo structures and any second cargo structure selected from the plurality of cargo structures is the cargo the selected cargo structures are configured to carry.

The present invention describes a container which is capable of creating a sound through the displacement of air within a channel and sound ports in the container.

A combination chair and pack frame apparatus for alternately seating a user and supporting loads on the user's back includes a seat frame mounted on a main frame. The seat frame may be folded against the main frame, placed in a seat position, or placed in a pack position. A seat made of flexible material is attached to the main frame and a distal portion of the seat frame relative to the main frame. When the seat frame is in the seat position, the seat may be sat on. When the seat frame is in the pack position, a load may be supported on the seat. A harness mounts the main frame to the user's back when the seat frame is in the pack position. A support leg assembly selectively supports the main frame when the seat frame is in the seat position.

A reconfigurable pillowcase 10 has two congruent panels 12 of non-absorbent fabric connected at two lateral sides 14 and a closed distal end 16. Three handles 30 extend in a proximal direction from the proximal open end 18 of each panel 12. Fastening strips 22 inside the pillowcase's proximal open end 18 seal off the interior of the pillowcase. The handles 30 form one pair of medial handles 50 and two pairs of lateral handles 52 which may be folded over each other and held with a single hand. The folding of the pillowcase to align the handles creates creases in the pillowcase that improves the control a person has over the direction and motion of the pillowcase during a pillow fight.
