The Rise Japan Namida Rubber Fat is made from very thick silicon rubber, approximately twice the thickness of that used in traditional tai rubber jigs. Its robust design captures water flow effectively and offers high elasticity, allowing for dynamic changes in silhouette as it flares or contracts in response to water flow shifts, such as when reaching the bottom or during retrieval speed adjustments. These silhouette changes make the Namida Rubber Fat highly effective at enticing bites, adding a unique and enticing appeal to your setup.
