I too just ordered some scuba gloves off eBay for washing when its like 35-50 degrees out. It helps a lot as my hands were always my weakest link while washing in cold. Now as long as its not too windy, its tolerable. I haven't been able to get myself to try the rinse less wash yet. When i want to wash mine in the winter, the truck is so nasty it just seems ridiculous to try rinse less. But like I said, never tried, I may be missing out! lol
