The XB1 Inline Smoke Freezer is a first of its kind.  It is a two-stage, multi-chamber pipe that cools like no other pipe in existence!  If you like the single Smoke Freezers, you'll LOVE the XB1 Inline!  This one DOES NOT come with ANY filtering components.  You can add them separately.  This one comes with an XB1 pipe, Power Supply, and Glass Stem.
