The temps are starting to cool down so I figured its getting time to plan for the winter. I've riden my St in temps down to 30 without heated clothing.. Doable but boy, all the layers.. This year I want to try some electrical heating..(other than the grips). Whats the word on heated vests and jackets.. Is a vest enough.. Ive noticed my arms get cold without all the layers. Any product recommendations? Webbikeworld seems to really like the tourmaster brand. Any info would be appreciated...Dan
