The Cosmonaut RDA is a collaboration between District F5ve and Mystery Mod Co. The Cosmonaut RDA features a 24k gold plated build deck with a post-less design. This post-less build deck features four large post holes with 4mm lead inserts which helps accommodate a wide variety of coil builds. The low profile build deck also allows for larger sized coils as well for the high performance vapor. This RDA also features dual adjustable airflow slots for maximum airflow.

The Cosmonaut RDA includes an ULTEM wide bore drip. ULTEM is a high temperature plastic with a significantly higher melting point compared to Delrin. ULTEM is also a very hard material, making it a suitable choice when threading into stainless steel.
