Thanks to the aerospace grade aluminum module with a full body hard anodization, the Invincipole is invincible. The 18.8mm/14.5mm downstem comfortably admits any 14.5mm bowl. 

But we haven't even gotten to the best part. The Invincipole features the world's first Telescoping Technology, extending from 3 inches to 5.75 inches. Bet that would really come in handy for you, huh? 

The downstem also features an ashcatcher, percolation diffuser, lightning ridges, O-ring seals, and a stainless steel screen.
