Nike's Team USA track and field kit for women is needlessly revealing and sexist, women athletes have said after the U.S. sportswear brand unveiled its outfits for this summer's Olympic Games.

Images recently made public of the women's kit on a mannequin, showing a very high-cut pantyline, triggered criticism from several athletes for what they saw as a decision to prioritise skimpiness over function.

In a message, U.S. steeplechaser, Colleen Quigley, said: "They are absolutely not made for performance." Debate has raged for years over more revealing outfits for women Olympians in disciplines from beach volleyball to gymnastics, and some rules on competition wear are changing.

Germany's women's gymnastics team wore full-length bodysuits at the Tokyo Olympics, in what they said was a stand against sexualisation in the sport, whilst Gymnastics New Zealand recently updated its attire rules to allow women and girls to wear shorts or leggings over their leotards. Nike said that it was offering athletes unitard options with both a brief and a short for this Olympics, whereas it only offered the brief for the Tokyo Olympics.

Nike's track and field kits for men and women include nearly 50 apparel pieces and 12 competition styles for specific events, the brand said when launching the outfits. Meanwhile, in a post on X, Nike-sponsored pole vaulter, Katie Moon, said the kit shown on the mannequin was "concerning", but added that women athletes are given many options on what to wear, and that she prefers briefs to shorts.

A spokesperson for USA Track & Field said: "Athlete options and choices were the driving force for USATF in the planning process with Nike." U.S. middle-distance runner Athing Mu and the country’s sprinter, Sha'Carri Richardson, were among the athletes modelling Nike's Olympic kits at the launch show in Paris.

While Mu (pic) wore briefs, Richardson wore a version of the outfit with shorts. Quigley said Nike should also offer athletes who make the team custom tailoring to ensure the kit fits perfectly.
