The Upline’s signature ladder perc is an elegant series of stacked bubbler chambers that force air and water to climb the pipe in unison, thoroughly filtering every hit. The family’s pattern of thick restrictions capture and ripple light, turning sections of clear glass into accents rich with color and depth. Each piece in the Upline collection is made on extra-thick tubing, adding weight and heft. Their carbs and mouthpieces are ergonomically designed for comfort. You can feel the value in these pieces every time you handle them.
