A method of manufacturing a flexible strap for retaining protective eyewear on a wearer's head, comprising the steps of:
- obtaining an energy absorbing material having a thickness of between 1 and 6 millimeters, said energy absorbing material being configured to deform to absorb kinetic energy on impact, including the steps of;
- extruding tubes with an inner circumference of a first material and an outer circumference of a second material, said second material having a lower melting point than said first material;
- cutting predetermined lengths of said extruded tubes;
- arranging said predetermined lengths into said energy absorbing material;
- and
- applying heat to melt a portion of said outer circumferences without melting respective inner circumferences;
- fabricating a first outer layer of flexible material;
- and
- placing said energy absorbing material and said first outer layer together such that they are held in contact with each other.
