A hip protector pad absorbs impact energy at a vulnerable area of a greater trochanter of an adult human hip. The pad has a continuous sheet of flexible honeycomb material having faces covered with an optional cover material and a layer of compliant and resilient foam on an inner side and an outer side of the honeycomb material. The pad is flexible to conform to a shape of the hip area. The pad is effective to reduce an impact of a fall of an adult human on the vulnerable area and minimizes the chance of a hip fracture resulting from the fall.

An impact absorbing protection pad, comprising: a first layer comprising a first compliant and resilient foam material, a first layer top surface, and a first layer bottom surface;a second layer comprising a flexible honeycomb material, a second layer top surface, and a second layer bottom surfac
1. An impact absorbing protection pad, comprising: a first layer comprising a first compliant and resilient foam material, a first layer top surface, and a first layer bottom surface;a second layer comprising a flexible honeycomb material, a second layer top surface, and a second layer bottom surface;a third layer comprising a second compliant and resilient foam material, a third layer top surface, and a third layer bottom surface,wherein first layer bottom surface faces the second layer top surface, the second layer bottom surface faces the third layer top surface, andwherein the pad is configured to attenuate a peak impact force resulting from an impact energy of about 12.5 joules to less than about 5600N required to cause a hip fracture. 2. The pad of claim 1, further comprising: air pockets disposed between the first layer and the second layer and/or disposed between the second layer and the third layer. 3. The pad of claim 1, wherein the flexible honeycomb material comprises polypropylene cells. 4. The pad of claim 1, wherein the first and second foam materials comprise the same material. 5. The pad of claim 4, wherein the first and second foam materials comprises crosslinked thermoplastic. 6. The pad of claim 5, wherein the crosslinked thermoplastic comprises a polyolefin. 7. The pad of claim 6, wherein the polyolefin is polyethylene. 8. The pad of claim 1, wherein the first foam material has a higher density and is less flexible than the second foam material. 9. The pad of claim 1, wherein the honeycomb material is from about 7 mm to about 9 mm thick. 10. The pad of claim 1, wherein the pad is less than about 23 mm thick. 11. The pad of claim 1, wherein the pad is convexly shaped to fit over a greater trochanter region of an adult human hip. 12. The pad of claim 1, wherein the pad is flat and shaped to conform around a hip region. 13. The pad of claim 1, wherein said honeycomb material is resiliently compressible. 14. The pad of claim 13, wherein said honeycomb material has wavy cell walls configured to allow resilient compression of the honeycomb material. 15. The pad of claim 14, wherein the honeycomb material comprises hexagonal cell geometry. 16. The pad of claim 1, wherein the first and third layers contact the second layer. 17. The pad of claim 1, wherein the first and third layers extend beyond an edge of the second layer and are joined together at a periphery of the pad. 18. The pad as claimed in claim 17, wherein the joining of the first and third layers is watertight. 19. The pad of claim 1, wherein the pad comprises an egg-shape or an oval shape. 20. The pad of claim 1, further comprising: a fourth layer comprising a cover material, a fourth layer top surface, and a fourth layer bottom surface; anda fifth layer comprising the cover material, a fifth layer top surface, and a fifth layer bottom surface,wherein the fourth layer bottom surface contacts the second layer top surface, and the fifth layer top surface contacts the second layer bottom surface. 21. An undergarment having a pocket to fit over a greater trochanter area and a hip protector pad that fits into the pocket, wherein the pad comprises: a first layer comprising a first compliant and resilient foam material, a first layer top surface, and a first layer bottom surface;a second layer comprising a flexible honeycomb material, a second layer top surface, and a second layer bottom surface;a third layer comprising a second compliant and resilient foam material, a third layer top surface, and a third layer bottom surface,wherein first layer bottom surface faces the second layer top surface, the second layer bottom surface faces the third layer top surface, andwherein the pad is configured to attenuate a peak impact force resulting from an impact energy of about 12.5 joules to less than about 5600N required to cause a hip fracture.
