Under Armour has signed an eight-year deal with US Speedskating to provide uniforms, despite controversy over the suit it provided the team at the Sochi Olympics. US speed skaters didn’t medal, and some blamed the suit. The team reverted to an older Under Armour suit, but results had not improved as of Friday. The Baltimore company said it is ready to try again. It will outfit US speed skaters for the next two Winter Olympics. Financial terms were not disclosed.
