To the edge of endurance and back again. The 1989-90 Trans-Antarctica Expedition inspired the contrast colors of our Offtrail Ultra shoe and Summit Series race kit. Designed to withstand temperatures as low as -80°C, the original TAE suits helped the six-member team cross the frozen continent. This November, the story comes full circle as @theultrarunnergirl heads to Antarctica. With the Offtrail Ultra and Summit Series apparel as part of her expedition kit, she’ll attempt to break Antarctica’s 100-mile speed record.
