Abstract: The present invention is directed to an attachment for use with adjusting straps on a cap comprising a sheet of flexible material having a first portion and a second portion contiguous with the first portion. The first portion and second portion each have a width and a length wherein the width of the first portion is greater than the width of the second portion and the length of the second portion is greater than the length of the first portion. The first portion has a widthwise slit having a perimetrical edge and an axis that is substantially perpendicular to the longitudinal axis of the sheet. The slit is sized for frictional insertion therethrough of the second portion. The second portion has a first end at the point of contiguity of the first and second portions and a second end opposite the first end. The second portion has an integrally formed engagement region in proximity to the point of contiguity of the first and second portions and adapted for engaging the perimetrical edge of the slit.
