Singapore, the country I ride my motorcycle in often is crazy hot and humid. Perhaps that's why riders seldom dawn riding jackets.

Made this model on recommendation of a fellow rider, Anthony to provide some additional circulation to often stuffy riding jackets without the sleeves flapping around in the wind. There are products online that functions similarly however why not make it on your own for a fraction of the cost. 

Open to others contributing to this simple design, & looking to better refine the inner geometry of the model to provide the balance between stiffness and airflow. 

Printed on the SL1S, Flexible resin - Prusament Flex80 White
