This pressed, flake-cut blend is composed entirely of high-grade, flue-cured Virginias, ranging from sweet, citrusy Brights to deep, earthy Reds, without the added sugars or top flavorings common in many Virginia blends

The room note is a notch stronger
Interestingly, the actual chamber dimensions here aren't that cavernous, more on par with your average Group 3 or 4 Stack which means the focus here wasn't as much on providing infinitely long smokes, but offering a piece which would remain cool and mellow in hand all the way to the end of the bowl
What this does is provide insulation around the airway and gives you a pocket of tobacco that has less surface area and thats a little more tightly packed which will slow down the burn by the time you hit the bottom of the bowl
