It seems that on Monday winter came to Sydney. I rode in my usual jacket from MAroubra to Penrith at 7 am, and by the time I reached my destination I felt like a deep frozen leg of lamb. I am a new rider and this is my first winter of regular riding. What's the best wionter riding jacket? Should it be leather? Any good budget options or the more you pay the better? Links and recommendations will be highly appreciated.
