Newly designed immersion suit, aided by warm breath, can protect for 24 hours

摘要

Anewly developed immersion suit dramatically increases survival time by capturing the warm breath of the wearer and recirculating it. Under current standards, a suit must protect the wearer for at least six hours to win certification from the U.S. Coast Guard. The recently-introduced Stearns product has been shown in tests to protect wearers for over 24 hours, according to the company. The tests were conducted in September 2013 at Simon Fraser University near Vancouver, British Columbia, using members of the Canadian Coast Guard as test subjects. They wore the suits in 32° water with air temperatures 10 inches above the water of 32°.
