When Dr Bill Stone made the coldest dive ever in West Lake Bonney he was wearing a Unisuit.
At the bottom at 39 meters, the water temperature dropped to - 5C because of the hyper saline water, actually 8 times more than sea water. But Stone had no problems coping with the temperature in his Unisuit.
His experience is shared with thousands of commercial and professional divers that have been using the Unisuit over the years. Because in freezing cold waters, the Unisuit is simply the best.
The 7 mm, elastic neoprene provide enough stretch to allow for hard work underwater and the quality withstand nearly every task you have to perform.
Just add more layers of Merino wool underwear as the temperature drops. Stone did just that when setting his world record.
