Get double the rotation with the Grav Large Circuit Rig. The angle of the intake hole causes water and vapor to spin rapidly and form a powerful centrifugal force. This cools the vapor 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.
