The 70’s XL scales the original concept into a roomier, two-stage setup. Height increases to about 10.5 inches, and the diffusion steps up from a single inline perc to a second lava-dome percolator for additional smoothing before the smoke reaches the mouthpiece. The wider format offers more water capacity and a little extra draw resistance that many daily users prefer, while still keeping everything easy to maintain. A 14 mm male bowl is included. Setup is familiar: fill until both perc sections are just covered, take steady pulls to stack bubbles, and clear as usual. Keep performance consistent by refreshing water frequently and giving the perc areas an occasional soak with isopropyl alcohol when residue appears. If you like the straightforward look of the smaller 70’s but want a cooler, slower draw with more capacity, this XL version is a practical step up without going oversized.
