A one-handed closure and release mechanism for selectively shortening the dimension of an item utilizing frictional engagement of a stretchable elastic cord member and a restrictive guide structure having at least two openings. In various embodiments the elastic cord member may either be secured inside a channel or fixed within an object or garment or may have two free ends extending out of the closure mechanism. The one-handed closure mechanism operates by use of the exertion of force on the one or more free ends of the stretchable elastic cord member which results in the relative proportion of the stretchable elastic cord member inside the closure mechanism being reduced which, upon release of the tension, has the effect of causing the crushing of the object to reduce the length of the channel through which the elastic cord member extends inside of the restrictive mechanism.
