About a week before thanksgiving, I was out cruising backroads with my dad and once the sun went down the ride got pretty chilly even with the full windshield so I decided to pull the trigger on a EMP rear window. I was out this past weekend in much colder temps then they were that day and all I can say is wow. I know I was also better dressed for cold conditions this time around, but the only time I felt any chilling wind on me was when I was going out a straight stretch between 2 large fields and caught a crosswind. I was running 40-50 mph down the road and was nice and comfortable. I know I probably won't do much cold weather riding, but for what little I may do that rear window was money well spent.
