Vintage Underwear

A foundational piece, done properly. Made in Japan from 100% ribbed cotton, this two-piece set is cut with a three-dimensional shape based on vintage athletic underwear, giving it a close, comfortable fit that feels considered rather than basic. Built with cotton sewing thread throughout, it carries the same commitment to authenticity and material integrity that defines The Real McCoy's. This Black Essential distills utility and heritage into an everyday essential — understated, functional, and made with the kind of care most basics no longer receive.
