What Gerbing's says about their Microwire® Technology:
Gerbings developed Microwire™ in response to a Department of Defense contract for heated clothing for Special Ops Forces. Of the conventional heating systems employed in heated motorcycle clothing at the time, none of it was up to the stress and strains that a soldier would put these items through, especially the demands of Special Ops. Carbon fiber wires were too brittle and thick, and common copper wire heated too slowly and eventually the military was able to get it to it fail. In a nutshell, the military wanted something stronger and more durable, thinner and lighter, and which would heat more rapidly. The answer to all these requirements was what we call Microwire™. And when we were done developing it, we patented it.

The wire in Microwire™ consists of bundles of hundreds microscopic stainless steel strands, each about 12 microns thick (about 1/4th the thickness of a human hair), twisted and wrapped in a thin Teflon-derived coating. Because heat escapes these strands from their circumferences, and because there are so many of these strands and they’re so tiny, Microwire™ heats instantly. No more waiting for the heat. It's there RIGHT NOW!
In the R&D process, we found that by altering the number of these strands in each wire, we were able to custom-tune the amount of heat. Additionally, by using these wires either in a heating pad, in a woven pattern or in our patented ribbon matrix, we could further tune how the heat is delivered. More, when using the ribbon matrix, we could refine the heat delivery to an even greater degree by altering the number of wires in the ribbon (from 2 up to 6). It is this “tunability” to each garment application that is one of the major advantages of Microwire™. But it doesn’t stop there.
Being as tiny as they are, and made from stainless steel, our strands (and therefore our wire) is incredibly flexible and exceptionally rugged. Also, at about .025” (vs. about .075 for the copper resistance wire that’s been in use all these years), Microwire is exceptionally thin. So much so you can’t feel the wires. Another advantage is at this tiny size we’ve been able to reduce more than a pound from the weight of our Jacket Liner, with similar weight reductions in our other Microwire garments.
So, in the end, Microwire is thinner, lighter, stronger and more durable. And it heats up in just 10% of the time that the old copper wire required.
Microwire is substantially more expensive to produce. However, it is Gerbings' intention to absorb this cost and hold its current retail prices, at least through the end of 2009.
Microwire is currently available in our Jacket Liners, G3 Gloves, Hybrid Gloves, T5 Gloves, Nubuck Gloves, Glove Liners and Insoles. Microwire is available in most of our products right now.
How it Works
You know how it feels when you put on warm clothes right out of the dryer? Cozy, right? All of us, even those who live in the warmest climates, face the cold at one time or another. It may be an early morning spring frost, a blustery fall afternoon or a bone-chilling winter evening after the sun goes down. Gerbing's Heated Clothing products will prevent you from suffering in these environments and help you better enjoy them regardless of your outdoor activity by providing that "just out of the dryer feeling."
