Antarctic Swimsuit Test

1946. Photograph by US Navy. “The U.S. Navy one-piece cold weather swimsuit underwent tests in icy Antarctic waters, in this historical photo. Three 5-man teams each stayed in the ice-laden waters of the Bay of Whales for a period of twenty minutes. No harmful effects were noted or reported. Under the rubber swim suit the men wore only one pair of long underwear. Each man had a 25-foot safety line tied around their waist. This was during Operation Highjump.”
