ANNIVERSARY SALE UPDATE:

Due to the high order volume, our stock is very limited... If you are still able to press the 'Add to Cart' button, there's still some stock left!

This heavyweight flannel-wool hybrid isn’t here to play—it’s here to dominate. Custom matte-snap buttons, structured seams, and a modern oversized fit make sure you’re getting those double takes. Whether layered over a hoodie or solo with a fresh tee, it’s the ultimate power move.

  • Flannel-wool blend – ultra-soft, warm, and built for year-round flexing.
  • Modern oversized fit – relaxed but structured for a bold streetwear edge.
  • Matte snap buttons – sleek, easy-to-style, and effortlessly cool.
  • Utility pockets – functional, stylish, and perfect for on-the-go essentials.
  • Layer-ready design – throw it over a hoodie or rock it solo—either way, you win.
  • Fits true to size
