The Jaguars introduced a throwback for 2024. It is the helmet they wore in 1995-2012.
This helmet is available as a pocket helmet in the 2-bar, traditional, chrome, and revolution styles. A lot of them are still available on various shopping sites. It is not available as a speed style factory helmet. I would anticipate it’s appearance as a factory speed pocket helmet is unlikely. But who knows?
