Short answer: Leather is popular for riding because it can offer abrasion resistance, wind protection, and a secure fit. The key is choosing the right leather thickness and a safe, comfortable cut.
- Fit: it should not flap in the wind, but you must be able to move your arms freely.
- Protection: consider armor-ready options if you ride regularly.
- Comfort: check lining and ventilation for your climate.
- Visibility: darker jackets look great but add reflective details if you ride at night.
If you share your jacket material and where you plan to wear it, I can suggest a safer option.
