The Aspire Cleito tank features an innovative design, where Aspire have decided to replace the chimney section of the tank with the actual coil itself. Constructed from stainless steel and pyrex glass, the Cleito also comes with a heat-resistant Delrin drip tip for use with high wattages and temperatures.nAspire have designed unique Clapton coils exclusively for the Cleito, with the focus of this tank seemingly for fuller vapour production. The Cleito uses a revolutionary new coil design that frees up even more restriction in the airflow by eliminating the need for a static chimney within the tank itself. This results in an expanded flavour profile and increased vapor production. Combined with a claptonized kanthal coil for maximum flavor. 3 different types of coil for the Aspire Cleito tank are currently available.
