This is a strap extension for facemasks with elastic straps that go around the ears.  This is a modification of an already approved strap extender (3DPX-013410).  The purpose of this modification is to lower the amount of material used, lighten the hardware, allow more flexibility and add an additional notch on each side for larger faces.  Feedback on existing extentions suggest that the current design may be too small for some, and now puts more stress on the bridge of the nose.  This design aims to alleaviate that issue, while still maintaining the integrity of the design.
