- Coiled downstem for extra cooling
- Inverted Showerhead percolator
- 5mm thick glass!
For those of you who want super cool smoke without having to resort to using ice then Grav Labs have come up with the perfect solution. Instead of the regular style of the down stem, it has a fixed one that feeds into the main tube and then swirls through a stack of spirals that lengthen the air path and allow epic levels of cooling before feeding the smoke out through inverted showerhead perc. The downstream is topped with a 14.5mm female ground glass joint and Grav include a 14.5mm male flower bowl to complete your setup.
