We use high-quality, natural, heat-resistant cotton. We optimize the mesh thickness and fiber structure to better absorb and deliver e-liquid. This allows the coil to work more efficiently, have a longer lifespan, and deliver consistent, great flavor every time.
The GTL X Tank features a slide-open top-fill design that lets you expose the filling port effortlessly with just one hand, making refilling quicker, simpler, and hassle-free.
GTL X Tank features an adjustable top airflow system that delivers a satisfying draw while reducing leakage. The airflow control ring allows precise tuning to match your personal preference.
