Based only on my experience of usage.
Love my Gn0mes..... at home. I can't really imagine using one on the go. The same could be said about the Supreme. These may be portable vapes, but because the need of a torch, they aren't exactly pocket vapes. I really love the Solo, but again, too big to be truly pocketable, especially with the needed stem. All are portable, none are pocket vapes. My Pax, on the other hand, offers fantastic, lung busting hits on medium. In my mind, the Pax is truly a pocket vape. I can load an oven full and just put it in my pocket. I barely notice it is there and it's usually all I need when I'm out and about.
