GRAV Large Circuit Rig.

The angle of the Grav Labs Circuit rig intake hole causes water and vapour to spin rapidly and form a powerful centrifugal force. This cools the vapour and makes each hit smoother, and the twin stacked chambers multiply this effect. There's no need to worry about splashback with the Large Circuit Rig because the sharp bend in the mouthpiece keeps all water inside the rig. This piece includes a 14mm female-jointed domeless nail made of heat-tolerant quartz, so all you have to do is add about 0.5" of water.
