When considering pipes with small bowls, don’t overlook clay pipes. The one above is my newest, a black clay. These are quick smokes, making them perfect for the pocket. I usually have three or four baggies on me, each with a different blend. So a pipe like this lets me smoke a variety of tobaccos when I’m out. Clays need no rest, and they don’t ghost. Wipe out the bowl, and you’re good to go.
