The HYDRA® has been carefully engineered to fuse all the benefits of a premium glass bubbler with the durability of aircraft-grade aluminum. In short, it's glass wrapped in a metal shield with a polycarbonate main chamber. The HYDRA® redefines what a long-lasting and well-designed pipe is meant to be. It also uses our patented "Quicklock" technology to assemble and take apart making cleaning with soap and water a breeze. This three in one pipe is the first of its kind.
