The Freeze Pipe Bong Pro and GRAV Upline take different approaches to a more refined flower session. GRAV puts its engineering into a distinctive ladder percolator. Freeze Pipe combines a showerhead perc with a freezable Revolver coil. If dedicated chilled cooling is the priority, the Bong Pro is our preference.
The appeal of the Upline
The 12.5-inch Upline draws water and smoke through a series of bubbler chambers. Its integrated vertical downstem also acts as an ash catcher, and the angled mouthpiece helps manage splashback. It is an interesting choice for anyone who enjoys unusual water-pipe engineering and wants a one-piece body.
The Bong Pro advantage
The 16-inch Bong Pro separates water filtration from frozen cooling. Its oversized showerhead handles the water stage, then smoke passes through the Revolver coil, whose independent tubes provide multiple smoke paths through the chilled chamber. For a shopper specifically seeking a cold draw, that is a more direct feature match than relying on additional water chambers alone.
What to consider
The Upline needs no freezer preparation and is shorter. The Bong Pro requires chilling its removable coil, but that removable section also lets you clean the upper cooling component separately. Neither design alone proves lower draw resistance or a better experience for every smoker.
Our pick
The Upline deserves credit for its original perc design. We would choose the Bong Pro when the goal is a flower bong with a dedicated cooling feature you can prepare before a session. That frozen upper chamber is the reason to spend more, rather than simply buy a more intricate perc.
