Back in 2023, Calvin Klein announced they’d be extending a brand ambassadorship spot to beloved K-pop star Jung Kook, a member of BTS.
Fast-forward to 2026, and their first limited-edition collection together, called CKJK, just dropped, celebrating their long-standing relationship. The men’s and women’s 20-piece capsule draws inspiration from a hobby that some of Jung Kook’s supporters aren’t huge fans of: his love of motorcycles.
The boy band member was licensed to ride a motorcycle in South Korea back in 2022, and his love for the pastime has been heavily documented on his Instagram and on BTS’ Disney+ show Are You Sure?! Jung Kook’s love of roughing it on the road is referenced in every piece of the capsule, from Americana ringer tees and cozy hoodies to grungy leather jackets. Pricing ranges from $29 to $699. All 20 pieces of Jung Kook’s brand-new collection are also available to shop now on Calvin Klein’s website.
Jung Kook for Calvin Klein Baseball Cap
This collection makes a clear reference to the K-pop star’s personal style with grungy elements seen throughout.
Sleek, comfortable and certainly practical, this baseball cap comes equipped with a snazzy co-branded logo on the front in gray and black, set against an all-white backdrop. The accessory is one of two baseball caps featured in the musician’s motorcycle-inspired line. As we approach hotter weather, this cap could come in handy for getting your hair out of your face and the sun out of your eyes.
Jung Kook for Calvin Klein Baggy Jeans
Beyond being a lover of motorcycles and grungy aesthetics, Jung Kook also seems to like denim quite a bit. You can sometimes find the star in denim-on-denim looks in unique washes like this style from his collection.
We’ve chosen these bottoms because of how unique the wash is. We can bet that this isn’t something you already have in your closet. The style is black with a rust-inspired coloring that gives the denim this worn-in, faded quality that makes it look vintage. These are baggy, something relaxed to fit Jung Kook’s nonchalant vibe. Also speaking of nonchalant, Calvin Klein’s denim is often rather soft and supple, allowing the wearer endless movement and freedom. Bottom line, you won’t feel too constricted when you wear these bottoms, which could come in handy if you plan on mounting a motorcycle.
Jung Kook for Calvin Klein Leather Racer Jacket
Did you know Jung Kook is an avid motorcyclist? The singer owns and rides several high-end motorcycles, including a Ducati Panigale V4 S, as seen on Instagram and a BMW R18 Roctane seen on BTS’ Disney+ show “Are You Sure?!”
This wouldn’t be a motorcyclist’s collection without some added leather. The finish of this style is nice and glossy. The jacket is comfortably oversized and supple with a collared neckline and a front-facing zipper. Ample pockets sit on either side. Co-branded detailing can be seen embossed on both the front and back.
We’d like to think this is a splurge piece. One that fans of Jung Kook can wear and re-wear, making it look better with age. If you don’t already have a classic black leather jacket in your wardrobe, then we urge you to snag this one. Leather jackets are go-to pieces that can be worn often. They go with everything and instantly earn you style points, making you look pretty cool.
Jung Kook for Calvin Klein Icons Graphic Ringer Baby Tee
Ringer tees are an all-American style usually featuring ribbed detailing around the neck and sleeves. The style originated as activewear.
Ringer tees are as Americana as a t-shirt can get. The silhouette was created back in the early 1950s. From its former athletic roots, the tee became a staple of biker culture in the late 60s and into the 70s, which is fitting for this collection. This tee is a cream colored hue with dark blue accents. The center of the shirt features embroidered motifs of hand-drawn icons inspired by Jung Kook. Ringer tees are super breezy and comfortable because of their high-cut sleeves and boxy design. The style is meant to be something you can throw on whenever, whether it be to go grab matcha or take a ride down the highway.
“Partnering with Calvin Klein over the past few years has given me the opportunity to express myself through the brand’s iconic style, and it’s been exciting to work with Calvin Klein in this more personal, creative way,” said Jung Kook in a statement from the brand. “As my first fashion collaboration, I wanted to fully immerse myself in the process, leveraging Calvin Klein’s design expertise to leave my mark on every piece. This capsule feels authentic to my style and my love of riding and is a meaningful way to shape something lasting through design and storytelling.”
