GRAV

GRAV 9" Upline Upright Bubbler

7

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. 75mm Glass - 14mm Joint.

    Great Glass!

    This upline bubblers diffusion is fantastic, it’s built like a tank and has a huge hit. (amazing for the size and typical Grav quality) Cleaning this bubbler is not bad, just don’t wait till it’s really dirty. Very nice with a vapexhale attached!

    An all-time favorite

    This is definitely up there in my all-time favorite bongs. I cherish this and I have yet to find someone who doesn't agree that it's the nicest hitting bubbler of its size that they've used.

    So smooth

    A bubler that fits in your hand like a water jug, but is glass throughout and gives massive rips that won;t leave you hacking up a lung. Amazingly smooth.

    Awesome bubbler

    My absolute favorite bubbler. The 9 inches of smoke purifying really makes all the difference.

    Really nice piece

    I was looking for a bong with a straightforward design to mix in with my "scientific" bongs and this was what I decided on. Boy, am I glad I did. I get nice hits off of it regularly and it works just as nicely as many of my fancier pieces.
