Today the weather was awsome! Sunny and Mid 80's so me and my Girlfriend decided to go for a ride. Speeds ranged from 35-75 and today was the first time she complained about feeling like a bobblehead doll. It seems since she is sitting higher than I am it sends the wind right over my head and into her. So if you ride 2 up and your passenger is taller or sits higher than you do then I would suggest either a taller shield that sends it over their head as well. I'm thinking I should have gone witht he Large now but for 1 up its a great.
