The
G-Form company makes protection gear for consumer electronics and extreme athletic endeavors, that makes use of
PORON XRD, which is a density changing and impact rate-dependent material. The basis of their product is RPT, which is Reactive Protection Technology, and is a combination of the PORON XRD material and their proprietary G-Form technology. What the product does is stiffens instantly on an impact, and it absorbs over 90% of the energy, providing excellent protection in a lightweight and flexible format. They had a small demonstration at Interbike this year, in which they dropped a bowling ball on some M&Ms that were in cased inside the product, and they survived with very little damage, showing how much energy was dissipated, and protection was provided. The change in durometer of the material during impact is easy to test, and if you slowly poke the material it's soft, squishy and pliable and leaves an obvious dent, while if you slam it fast and hard, it stiffens up substantially with less penetration.
The G-Form exoskeleton armor comes in three different versions currently, the
Knee Pad, the
Shin Pad and the
Elbow Pad, with each retailing for $49.95. They should hopefully be releasing a compressive shirt and crash shorts; shown above; some time this year? The slip-on armor utilizes an elastic fabric tube, made from a nylon and spandex blend, in which the molded RPT padding is flat stitched onto the material. The top cuff of the tube has a silicone gripper band, which offers adhesion, to prevent the armor from creeping and moving downwards during use. The design mimics a set of arm or knee warmers, and the fabric fits snugly to assist in keeping things in place, and also provides compressive qualities. They come in eight sizes, 2XS, XS, S, M, L, XL, 2XL and 3 XL, so they'll cover the gamut of body shapes and girths. Their website has detailed sizing charts for each of the versions to make sure you get the appropriate fitting set of armor.
