Replicas of climbing gear worn by George Mallory on his ill-fated 1924 Everest expedition are being unveiled.
The replicas reveal Mallory was appropriately dressed for the climb
Experts from Lancaster, Southampton, Leeds and Derby universities spent two years on the project, and the results are being shown at Rheged, Cumbria.
The aim of the work was to learn more about early clothing produced for extreme conditions.
Wirral-born Mallory and fellow climber Andrew Irvine disappeared while trying to be the first to climb Everest.
The question of whether the pair made it to the top of the world's highest mountain has endured for 80 years. Mallory's body was found by an expedition in 1999.
The replicas project began when artefacts found with the body were transferred to the National Mountaineering Exhibition at Rheged.
The £30,000 project has been funded by the Heritage Lottery Fund and the Pasold Research Fund Ltd and was carried out on behalf of the Mountain Heritage Trust.
The project team was led by Prof Mary Rose and Mike Parsons from the Institute for Entrepreneurship and Enterprise Development at Lancaster University Management School.
Researchers said the replicas address the misconception that Mallory climbed Everest dressed poorly for the elements.
Vanessa Anderson, one of the researchers, from Derby University, said: "What impressed me is the strength and quality of the materials they used and how well they were tailored to withstand the conditions on Everest."
The results were being unveiled at the Clothing for Extremes conference at Rheged.
Top British climber Alan Hinkes and 1999 Mallory expedition historian Jochen Hemmleb were also taking part in the event.
