A cuff seal utilized in a portion of a full pressure suit which envelopes a limb of a wearers body, the full pressure suit defining at least one full pressure compartment. The cuff seal includes a gas impermeable outer sheath configured to envelope a portion of the limb, the sheath having a first end in pressurized communication with the full pressure compartment, and a second end having an opening through which a portion of said limb exteriorly protrudes from the interior of the full pressure compartment. A gas impermeable inner sleeve is provided having an outer end, an intermediate section and an inner end disposed within the sheath, the outer end of the sleeve being joined in a sealed relationship to the interior of the sheath proximate to the second end, and the intermediate section of the sleeve being adapted to surround and coact in a sealed relationship with a portion of the limb. The sleeve is therefor adapted to interiorly seal the full pressure compartment from the opening to the exterior of the suit when donned by the wearer.
