Here's a second question since I'm a newbie.
What are the differences in terms of protection and advantages/disadvantages with the different jackets out there? Mesh, leather, textile, etc.
Leather= Best overall protection. Make sure its a real riding jacket, not just a leather style jacket. You can tell the difference because a riding jacket will have AT LEAST CE1 rated elbow pads, and more likely than not shoulder pads. The better ones have back protection as well. Leather will slide longest without breaking down, preventing road rash. Perforated leather can help when its hotter out, and a lot of jackets have zipper vents to allow air flow.
Textile= There is a wide range of quality when it comes to textile. The more expensive ones can protect you close to leather, but nothing can protect quite like leather. Can be better at weather protection than leather, can be less hot than leather.
Mesh= Weakest of the three, but still a good choice. Again, quality can vary, but they normally have very good airflow, protection at impact zones, and typically come with a removal-able cold weather and/or rain liner, making them versatile. They have the worse slide protection of the three.
Overall, the best jacket is the one you are going to wear. Most accident happen close to home, so its worth it to invest in something that you can just throw on and ride with, no matter if its to the grocery store or across the country.
