Are you prepared for “Advanced Perconomics”? This futuristic design comes from the step-ahead engineers at Grav Labs paired with the mad scientist mind of Micah Evans in the first of its kind Upline collection. Applied to a variety of shapes and sizes, the essence of the Upline is a series of stacked restrictions that each act as its own percolating station in a spine-like silhouette. Watching the bubbles flow through this unique creation is just as badass as you might imagine. Through the combined effects of directional airflow, gravitational diffusion, and hydrodynamics--you’ll feel like you’ve stepped into the future with the incredible clouds this device can deliver. Possibly THE most effective push-bowl bubbler out there, this thick glass pipe is further enhanced with a diffused downstem, carb construction, and a layback flute mouthpiece. You won’t want to stow such a sophisticated design away; you’ll find yourself proudly passing it around for friends and displaying it like the artistic masterpiece it truly is. PLEASE NOTE: decal colors are selected at random.

A work of art

The coolest pipe I've ever seen. I'm so happy to pull it out and pack it up to pass around and show it off to my friends. I won't be sruprised if a bunch of my buddies end up buying this bubbler from DopeBoo too.
