A strap for a golf bag, the strap comprising: a main body defined by a core, the core extending along a length of the main body and being formed from one or more polymer foam materials to provide a degree of cushioning for a shoulder while transporting the golf bag, the core having a first end attached to a first attachment location of the golf bag and a second end attached to a second attachment location of the golf bag, a front surface, and a shoulder-engaging surface disposed on an opposite side of the core than the front surface; and a channel defined by the core and extending between the first end and the second end; a tension element extending between the first end and the second end, the tension element movable between a tightened state and a relaxed state, and including a first portion associated with a lower portion of the main body and a second portion associated with an upper portion of the main body, the upper portion being disposed between the second end and the actuation mechanism, and the lower portion being disposed between the first end and the actuation mechanism, the tension element applying a force on the first end and the second end in the tightened state to change the relative position of the first end and the second end; and an actuation mechanism supported by said main body and operable to move the tension element between the tightened state and the relaxed state; wherein the first portion of the tension element defines a length that extends between a proximal end attached proximate to the first end of the main body and a distal end received by and attached to the actuation mechanism, and the second portion of the tension element defines a length that extends between a proximal end attached proximate to the second end of the main body and a distal end received by and attached to the actuation mechanism; wherein changing the relative position between the first end and the second end includes changing a shape of the main body such that in the relaxed state of the tension element, the main body includes a straight configuration between the first and second end, and in the tightened state, the first and second end change the position of the main body from the straight configuration to a curved configuration, wherein the channel is disposed along the length of the core that receives a length of a first guide member and the first portion of the tension element, and the channel receives a length of a second guide member and the second portion of the tension element. a main body defined by a core, the core extending along a length of the main body and being formed from one or more polymer foam materials to provide a degree of cushioning for a shoulder while transporting the golf bag, the core having a first end attached to a first attachment location of the golf bag and a second end attached to a second attachment location of the golf bag, a front surface, and a shoulder-engaging surface disposed on an opposite side of the core than the front surface;
