So I was riding back from the NE fall rally via north-central Maine, northern NH and northern VT, and the temps dropped to around freezing, Nothing unusual around here, but cold enough with the minimal other gear I had on to let me run the jacket and gloves at close to full output. I've come to the conclusion that the Gerbings I have is just not well designed. I think it is designed to fit under the usual cruiser / bomber-style waistlength jacket for people in an upright riding position, and not on a sport-bike when using a 3/4 length touring jacket. There is a substantial section of lower back that is not covered by heating elements, and the forward leaning position exposes another archaic design element, the so-called heating pads, which are really individual wire elements that create hot spots on your back. And yet another grip is the material: the coated nylon really does not breath well, so if you are in 'active' riding mode (as on a sled or pushing hard in the twisties) for a while, it traps a lot of moisture underneath. You really need to wear a fleece over the liner to conserve scarce electrons (and to provide lower body coverage). They could offer an option where the jacket has a fleece or microfiber outer layer instead of the el cheapo nylon. Why not offer an option that has a longer back and body in addition to different materials, and heck: it is 2008: surely there is another option for heating other than thick wire?
