Hardcore Luxury® ..... No Brag, Just Fact

WeatherWool Merino Jacquard Fabric Palette



Please note:  This is a new product, with an old name. What we used to call the "ShirtJac" we now call a "CPO Shirt". Because the ShirtJac hasn't yet been in production, the photos on this page show the working prototype at Better Team USA, the tailors. As soon as we've made the final prototype, we'll get new and better photos up, but it will not look different.

Planning to ship in February 2023.

The ShirtJac is a FullWeight item. The somewhat similar CPO is MidWeight.

The new ShirtJac is priced at $525 for sizes up to 2X. Size 3X, $545. If you'd like a ShirtJac in a larger size, please contact us directly.

ShirtJac features:

  • Front chest pockets (on the outside) with button-down flaps
  • Large Handwarmer Pockets entered by a "slash" at the waist
  • Two very large drop pockets and one large zippered pocket inside
  • Center front secured with Slot-buttons
  • Collar can be buttoned down or flipped up, and is substantial enough that if you fold it up you will notice the extra warmth around your neck
  • The bottom of the garment is squared, like a jacket
  • 3 Slot-Button Sleeve adjustment at wrist
  • Sleeves cut long for better coverage 
  • Cut long 
  • ShirtJac in size Large should weigh a little more than 3 lbs (1.36 kg)

If you are interested in a ShirtJac please backorder at a price of 0, with no obligation. Please click for Production Status or a snapshot of our overall Inventory.

Our ShirtJac will of course be made of our own FullWeight Merino Jacquard Fabric ... soft and tough ... Hardcore Luxury®.

The REVIEW feature below, which enables anyone to publish a review, was added in March of 2022.  We probably won’t see any Reviews here until we make and ship these pieces. But we have made a handful on a custom basis, so maybe someone will post.
