Conner Mantz Sports Custom Jacket Designed by Chicago Based Nike Partner, Notre. Nike teamed up with partner and local Chicago Retailer, Notre, to design a one-of-one jacket for Conner Mantz ahead of his attempt to break the America marathon record in Chicago.   The jacket’s design was inspired by Mantz’s past, with hues of blue nodding to his alma mater and a distressed detail representing the grit and grind behind his running journey. All-American details are meticulously found throughout the jacket, with an American flag on the inside followed by a list of Mantz’s stats and accomplishments. Flanking the jacket are four red stars on the right sleeve to represent Chicago’s flag, and “Chicago MMXXV” on the left to mark the moment.   Notre, a creative hub known for their craftsmanship and community-driven collaborations, designed this piece with both Mantz and the boutique retailer’s heritage in mind. The jacket was created with quality wash canvas and cotton tool and features a corduroy collar honoring the blue-collar background of Notre’s co-founders.
