BTS Jungkook's '2026 Jungkook for Calvin Klein (CKJK)' collection products have sold out in countries around the world.
On May 20 (Korean time), 36 items from the '2026 CKJK' collaboration collection with Jungkook went on sale on the official Calvin Klein website globally.
On the U.S. website, all 36 items sold out in less than 30 minutes after sales began. The entire collection sold out on the websites in Japan, Poland, Australia, and Italy. On the Korean website, all items except some sold out on the day of launch, and the sold-out status continued even after the second restock in the afternoon. On the Chinese website, the leather jacket worn by Jungkook in the promotional photos sold out in all sizes within one minute.

According to 'Pop Core', which covers pop culture news, the Calvin Klein website went down globally as fans flocked following the collection launch.
Calvin Klein revealed 'CKJK', the first collaboration collection in its 58-year history to feature direct design participation by an idol with Jungkook. Calvin Klein officially announced via its official social media: "A bold expression capturing the true style of a global icon. An unprecedented collaboration. This is Jungkook for Calvin Klein."
Jungkook participated in all aspects of the creative process, from initial concept discussions to final design details. He personally selected the denim wash and collaborated with the Calvin Klein team to customize the fit of items such as the brand's trucker jackets. This collection was built upon Jungkook's love for motorcycles.
