This paper seeks to expand recent interest in the material practices, policy techniques and technopolitics of borders, migration and solidarity initiatives in Europe by connecting this debate to Sloterdijk’s spherological philosophy. With his thematization of enclosures, atmospheres, foams and life support Sloterdijk helps us to give a more morphological account of borders. We illustrate the benefits of this move by reflecting on the recent questions of hostile environment and the criminalization of migrant solidarity practices and movements. The paper also highlights certain limitations in Sloterdijk’s thoughts, which appear when it is brought into migration research. Arguing that Sloterdijk remains somewhat sedantarist in his approach to atmosphere we introduce a concept of the envelope as a way to foster a more dynamic, agonistic and mobilityfocused conception of enclosure.
