What makes the X3 denim snapback special?
The Under Jean X3 is made from thick charcoal denim that keeps its structured shape when you wear it. The flat brim is classic snapback, and the front has a neat black rectangular label that stays low-key. It's the main cap NHS is pushing right now for anyone who likes a tough look.
At the back you get a row of metal snap buttons instead of the usual plastic strap. Each notch adds about 2cm, so the 57–58cm unadjusted size can be let out for bigger heads and still sit snug.
How to style the X3 snapback
- Denim jacket or black bomber: matching gray and black tones for a bold, clean look.
- Hoodie, oversized tee: streetwear and hip-hop vibes for hitting the streets.
- Dark shirt, jeans: everyday casual that works for coffee runs or nights out.
