A leash is described. It includes a length of strap extending between a first and a second end along a longitudinal axis. The strap is folded along the longitudinal axis to form a loop. The leash also includes a strap length adjustment mechanism attached to the strap intermediate the loop and a terminating end of the strap, wherein the terminating end is attached to attachment hardware configured to reversibly receive a collar of an animal. The adjustment mechanism has a length fixing configuration and an adjustment configuration, wherein the length fixing configuration is configured to prevent changes in the lengths of the loop of strap and the length of slack strap, and wherein the adjustment configuration is configured to allow for adjustment of the diameter of the loop of strap and the length of slack strap.

A modular wearable object includes a main body, two combination plates, and a carrier. The main body includes a main portion and at least one extension portion. The extension portion extends outward from an end of the main portion. A part of each of the combination plates is fixed on the extension portion. Each of the combination plates has a first connecting portion located on a surface thereof facing the main body. The carrier includes a bearing portion and a positioning portion, wherein a space is formed therebetween to be passed through by the main portion. The positioning portion has a second connecting portion located on a surface thereof opposite to the main portion. The second connecting portion is adapted to be detachably engaged with each of the first connecting portions. A relative position between the main body and the carrier can be adjusted, and the carrier is replaceable.

A shoulder belt has a longitudinal direction and a transverse direction intersecting the longitudinal direction, and includes a first section and a second section spaced apart from each other in the transverse direction in a cross section intersecting the longitudinal direction, and a third section connecting between the first section and the second section. An expansion and contraction ratio of the third section is higher than each expansion and contraction ratio of the first section and the second section. Bending resistance of the third section is lower than each bending resistance of the first section and the second section.
