The event began at the Fifth Avenue flagship on Friday and runs through Oct. 10. Uniqlo’s core products — comprising the likes of its 3D Knit, HeatTech and Ultra Light Down — will be celebrated through interactive customer tech displays. Along with photo ops and try-ons with core products, there will be a HeatTech installation and a 3D knit machine for trial. It’s the first time Uniqlo’s 3D knit machine will be shown to the public. Showcasing the process of creating a seamless knit, the machine takes three threads and, in real time, knits a garment to shape from hem to collar.
