During our email exchange last month about his Nike Flyknit Mask, ZJ Design’s Zhijun Wang privately hinted that he was already working on a second version. Since then, the Beijing-based designer utilized the second half of his Nike Flyknit Racer to create the Nike Flyknit Mask 2nd Edition. Constructed out white Flyknit fabric, Wang added several improvements, including lace lock and elastic bands for ease of adjustment. Realized the need to swap the filtration mesh regularly because of Beijing’s horrendous air quality, Wang reworked the interior lining to accept a reusable filter instead. However, similar to the previous Black Edition, this is still a working prototype only but being the consummate tinker that he is, Wang is planning on a follow-up design already.
