It is the XL. It is quite heavy to hold while you hit, but I do prefer more water volume for cooling. I liked it best when I paired it with my old Verdamper tube mouthpiece which is huge comoared to Herbo's. It allowed much larger hits and was easier to hit. You didnt ned to be so close. I avoid the whip as it is less tsty, harder work, also more throat irritation from longer throat contact. If the Verdamper mouthpiece plus shipping wasnt so much, I would get one in a heartbeat.
