A "sealed cabin" design. They have a very efficient pressure vessel design. As far as PPB goes, he would be wearing a "counter-pressure" garment around his torso. A "poor man's" pressure suit, although it really wouldn't be effective above 85,000 feet. I wore one on a rapid decompression to 60K, stayed for one minute then a rapid descent to GL. The Canadians were conducting training with them to 85K, and was evidently working good to that altitude, but only for extremely short duration exposure.
