There's also a strap that's sewn to the bag with a clip on the end to use as a key fob

In some cases, you can technically wear it on whatever shoulder you want, but it will likely sit uncomfortably on one side, or the buckle will end up in an awkward place thats hard to access with your dominant hand (sorry lefties, this one will impact you more often)

Some monos get stiff and brittle in the cold, while others are specifically designed for low temperatures

Also, while its warm, its not the jacket you want in extremely cold temperatures (20 degrees should be the cut-off.) That said, if you get caught in a downpour, know that Patagonias Micro Puff dries extremely fast

AGV K1 is a good cheap motorcycle helmet for races and high-speed journeys
