Sir Ranulph Fiennes - hailed as the greatest living explorer in the world - is on his way to the Antarctic to undertake his toughest challenge yet. The Coldest Journey on Earth will see his five-man team face temperatures of -92 °c…and British outdoor specialists Montane are supplying key clothing and equipment for the expedition. Montane’s design and development team has worked with Sir Ranulph for six months to create a sledge jacket designed to cope with the most hostile conditions on the planet. Sir Ranulph’s attempt to cross 2,000 miles of the Antarctic during the Polar winter – a feat never before accomplished - will involve travelling through terrain that he himself once described as ‘impossible’ to conquer. In what has been described as the last great Polar challenge and an epoch-making attempt on the record books, the Coldest Journey on Earth will set off in March, and is scheduled to last for six months. En route to the Official Starting Point The team left London on board expedition ship SA Agulhas last week, en route to the official starting point in Novolazareskaya in Russia. Montane is supplying clothing and rucksacks to Sir Ranulph, his expedition team and the ship’s crew. The Sledge Jacket is a specially-adapted version of the renowned Montane Extreme Jacket , an outdoor classic tested in the most punishing conditions in the world by mountaineers, climbers and Polar adventurers. The latest edition of this technical softshell launched for 2012 has 20 years of research and development in its history, and is a trusted favourite of Mountain Rescue Teams and professional explorers. Sir Ranulph will be one of two men undertaking the Polar journey on skis, leading two giant sledge-borne bulldozers transporting cabins for use as living quarters and a fully-equipped, purpose-built scientific laboratory. The leading pair will be responsible for seeking out potential dangers on the ice, including any crevasses which would halt the entire expedition in its tracks.
