Is this the coolest piece I own? This jacket for Aritzia has been authentically produced and licensed by the Olympic Museum collection for the 2010 Olympics, with a design throwback to Sapporo ‘72. Unique and RARE, in EUC no flaws or wear! 88% polyester and 12% cotton. XS but definitely fits XXS. The material is a very high quality technical fabric, ideal for sports. Measurements in comments. Selling bc I have too many tech jackets!
