ATEEZ’s San stopped by Casa Herno Seoul and shared a set of photos on Instagram on November 7, 2026. The caption kept it short (“With @herno”), and the post is tagged as a paid partnership with the Italian outerwear label.
The star of the look is a hip-length down jacket in olive, almost khaki green, with horizontal channel quilting, a zip front and snap-close pockets. What makes it feel more refined than a regular puffer is the dark brown corduroy point collar. He kept everything underneath simple with a white tee, and in one shot he swaps in a dark charcoal knit cardigan trimmed with white piping.
The post was made with Herno, but we could not match the jacket to a specific model on Herno’s US site yet, so there is no exact link for now. The closest thing you can buy today is the Barbour Hornby Quilted Jacket in Sage ($290): same deep olive shade, a brown cord collar, flap pockets and a zip-and-snap front. The Barbour Heritage Liddesdale in Olive ($265) is another good match, with a dark brown corduroy collar, snap front and a similar hip length.
One thing to know: both Barbour jackets use diamond quilting instead of San’s horizontal channels, and they are lighter than a true down jacket. For the base layer, a plain white tee like Gap’s Adult Relaxed T-Shirt ($29.95) does the job.
