These are sweatpants from the overseas street brand of Project ISR CLP. The original price was about 17,000 yen. Customs duties and shipping fees are extra. Unlike trendy sweats, Uniqlo C, or so-called "chiteijin" (people who dress in a certain style), the fabric and silhouette hold their shape very well. They are better than sweats that are sold at high prices, starting from around 12,000 yen, and offer a good point of differentiation.
