New Era Jacksonville Jaguars On-Field Sideline Bobble Knit. Rounded out with a cool winter bobble top, the cold weather style is also enhanced by a warm fleece lining. A 'JAX’ wordmark is positioned on the front of the crown, while the team name is included on the back. The knit’s upturned cuff also features a team logo on the front, an NFL shield at the rear and our signature New Flag embroidered to the left.
