Abstract
An encircling sealable closure such as a neck band or collar made of a band of compressible material interposed between a three layer inflatable band at the neck of the user provides a neck seal by inflation of the inflatable band positioned between the compressible material and a substantially non-extendable outer wall. Inflation of the inflatable band deforms the compressible material to conform with and surround the neck of the wearer preventing the ingress of water past the neck seal so formed.
