Helix pipes and accessories are some of the most popular GRAV products due to their iconic Venturi chambers that spin smoke in spectacular fashion. This chamber cools your smoke for one of the smoothest smoking experiences you could imagine. Helix products come in a variety of shapes and sizes so there's a solution for every type of smoker. Helix has shaped decades of smoking experiences and the line of Helix pipe and accessories continues to evolve over time to create new, innovative ways to include this smoking technology in more modern pieces. The pieces in this collection are specific to GRAV Helix. You can find more Helix pieces in our American Helix collection which includes several other designs made by the original creator of this awesome pipe.
