Jeep caps are typically made of tight weaves. If that's not what you're looking for, then check out ourTwo Tone Military Knit Cap! It's knitted for a beanie feel to it, but it is lined inside to prevent the cap from stretching and losing its shape.
It's made of 100% acrylic that is thick and soft to the touch. It's one-size-fits-most and the bill and crown are typical 2 inches and 3 1/2 inches, respectively. Even though the jeep cap is made of a thicker material, it can be worn really in any season as it features a stylish stripe design around the crown and an asymmetrical one on top of the crown.
