The Yocan Evolve Plus is a uniquely (just like its counter part, the Evolve) vaporizer but now with a bigger chamber and battery. Still designed for portability that brings a small size device without leaving out an incredible experience. What is it that most users look for in a portable device? Long lasting sessions and protection that it doesn't short out. The Evolve by Yocan delivers both! The dual quartz coils allow for a quicker heat up time and provide the smoothest experience. Whats more? The Evolve Plus features a built in silicone jar on the bottom of the device to store you materials.
