Abstract: A size adjustable sports cap having a crown constructed from a plurality of triangularly shaped panels, substantially all of which are expandable and contractible, and which form a crown of the cap adapted to be disposed over the crown of wearer's head. The crown has a lower margin and secured to that lower margin is a multi-section band having a plurality of spaced apart stretchable band sections separated by a plurality of spaced apart non-stretchable band sections. This band thereupon forms an opening which is size adjustable to receive the crown of a wearer's head. One of the important aspects of the invention is that there is no deformation of the crown of the cap and the construction allows for a more natural wearing fit of the sports cap.
