This innovative collab from Grav and Micah Evans is unlike any other bong on the market, with its unique ladder perc that stacks up bubbles to wash & filter your smoke within each mini chamber throughout the neck. The larger upper chamber and bent neck mouthpiece make for an excellent splash guard, while the stemless design makes it super easy to clean. Plus, the compact 12" size makes it perfect for small spaces. No matter what you're looking for in a bong, the Grav Upline Series has got you covered!
