Abstract
An immersion suit having a neck band to fit around a neck and a seal at the neck. There is a thick band of closed cell foam on the interior of the neck band. The neck band and the closed cell foam can be compressed rapidly by a strap to ensure a seal when required. When a seal is not required, the foam is a relatively loose, comfortable fit around the neck of the wearer. In the preferred embodiment, the suit has an opening in the front extending to the top of the neck band to allow ingress and egress from the suit.
