Product Details

Equipped with the same unique filtration designed by Micah Evans in the original Grav Upline Bong, the Upline Hammer Bubbler was built to provide epic diffusion while on-the-go. This hammer bubbler features a fixed fission downstem that filters each rip through water and sends your smoke through a climbing filtration system before reaching the straight neck mouthpiece. The smaller chambers on the Upline Bubbler, known as a ladder perc on the Upline Bong, work to continuously diffuse your smoke with water and cool down each hit to smooth perfection. The ladder perc also conveniently prevents water from reaching the mouthpiece as you inhale.  

Grav Upline Hammer Bubbler

The Grav Upline Hammer Bubbler measures a travel-friendly 5” inches tall by 8.5” inches in length, perfect for tossing in your backpack and taking with you as you see fit. The deep flower bowl and downstem are both fixed inside the bubbler to prevent damage. No accessories are necessary for using this bubbler, and it functions best with approximately 1” inch of water in the base. Two worked glass marble feet stabilize the Upline Bubbler between uses, and the left side air carb and mouthpiece are ergonomically designed for maximum comfort. Enjoy smooth rips and limitless portability with the Grav Upline Hammer Bubbler today!
