The Vaporesso SKRR-S 26mm Sub-Ohm Tank is the latest sub-ohm tank from Vaporesso, providing a threaded top-fill, upgraded dual bottom airflow ring, and the utilization of the QF Coil System. Formed from durable stainless steel, the SKRR-S tank has pyrex glass reinforcement to prevent breaking during light and moderate falls. The SKRR-S Tank adopts the newly introduced Quadflow (QF) Air Distribution System, in which airflow channels into the atomizer core and spreads internally in four directions. The Vaporesso QF Coil System utilizes the combination of cotton and flax materials for a long-lasting yet flavor-enhanced performance with the following coil options: 0.18ohm QF Meshed and 0.18ohm QF Strip. At the top of the Vaporesso SKRR-S Sub-Ohm Tank is a threaded top fill system, designed for fast and easy refills by removing the top cap to reveal a generously large fill port that allows the tank to hold up to 8mL of juice within the pyrex glass.
