The Yocan HIT Mouthpiece is designed and engineered in conjunction with the Yocan HIT’s diffused airflow design. The battery of the Yocan HIT features specially designed independent air paths that allow for maximum air intake. Because the Yocan HIT is a convection vaporizer, having better airflow works in its favor and allows you to heat the herbs better resulting in superior vapor production. The vapors produced by the convection oven and the ceramic heating element is carefully funneled by the Yocan HIT Mouthpiece. Thanks to its triangular design, the vapors are channeled to a slim and narrow passage which not only makes drawing and pulling from the Yocan HIT Mouthpiece easier but also helps you reap all the benefits your botanical plant matter has to offer without wasting any of its active ingredients included in the vapor.
