Abstract
Abstract This specification discloses an environmental suit fabricated from flexible material. The suit has a hoop supported entrance. The hoop is sealed to the entrance module and an entrance tunnel provides access to the suit. The entrance module folds accordian style for storage, and a unique loose, unsupported umbilical section is attached to the suit. The entire suit, umbilical section and tunnel may be stored in the entrance module. Semirigid boots are provided for easy ingress and egress. Removable cuffs on the suit make it easy to change gloves from heavy work gloves to the surgical rubber gloves for finger sensitivity. A built-in life support system supplies filtered air to helmet and gloves. The air lines provided are flat and sandwiched between two layers of material. The entrance tunnel is supported by an overhead track which makes it easy to move the suit about.
