In a sense, our ShirtJac is a Basic Shirt Design ... But at the same time, it is our take on the traditional CPO Jacket from the US Navy, which has been widely appreciated for decades and became very popular in the late 60s and early 70s. It's never really disappeared, and for good reason ... it can be a jacket or a shirt, depending upon what you need, what else you wear and the Fabric from which it is made. The CPO ShirtJac is just an extremely versatile classic.  

Our ShirtJac is, of course, made of our own Merino Jacquard Fabric, the softest tough Fabric anywhere (Hardcore Luxury®), and is available in either MidWeight or FullWeight versions. Please click for information about FullWeight vs MidWeight Fabric.

Our ShirtJac provides a great example of the versatility that we strive for. In January 2016, I spent a few days in Fairbanks, Alaska, making several presentations to United States Military. With a light wool base layer, the FullWeight ShirtJac was comfortable at indoor temperatures of 70F/21C, and was good enough when we were outdoors in temps of -10F/-23C!

Leo Grizzaffi, the outdoor writer, likes to wear his ShirtJac instead of a sport jacket. Advisor Dave Canterbury prefers all of his instructors at The Pathfinder School (bushcraft and survival) to wear WeatherWool Lynx Pattern. At left is a selfie of Dave in his ShirtJac.

  • In our FullWeight Merino Jacquard Fabric, the ShirtJac is more of a jacket
  • In our MidWeight Merino Jacquard Fabric, the ShirtJac is more of a shirt
  • Tails are long enough to be tucked in but people usually wear the tails outside, particularly with the FullWeight
  • Front pockets have modest bellows and button-down flaps; and are deep enough for a big phone
  • 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
  • Above the cuff is a 4 inch opening secured by button offering good closure but also enabling the cuff to be comfortably folded up
  • The cuffs are secured by either of two buttons that enable adjustment. The adjustment is particularly useful when coordinating the cuffs with gloves, mittens or a base layer with a monkey-paw (thumbhole sleeve)
  • Sleeves cut long for better coverage and to let you pull your hands inside
  • Indestructible melamine slot buttons
  • Cut long and generous 
  • FullWeight ShirtJac in size Large weighs 3 lbs (1.36 kg)
  • MidWeight ShirtJac in size Large weighs 2 lbs 6 oz (1.08 kg)

Available in FullWeight Fabric in Solid Colors Black, Drab and Duff as well as Lynx Pattern.  Also available in MidWeight Fabric in Solid Drab Color and in Lynx Pattern.

When next we make the ShirtJac, we will likely do it differently:

  • We will add Slot Buttons under the rear of the collar so the Double Hood can be attached
  • Except for the Slot Buttons, the design of the MidWeight ShirtJac will not change
  • We will add Handwarmer Pockets to the FullWeight ShirtJac.  There are at least three ways these Pockets can be added:
    • We are leaning toward forming the Pockets by sewing FullWeight Fabric to the front of the ShirtJac. This is the simplest approach
    • We could instead sew some FullWeight Fabric inside the ShirtJac, which would make a warmer pocket but then the stitching of the pocket would show on the outside of the ShirtJacs made in solid colors.  Lynx Pattern would hide the stitching
    • An inner Pouch-Pocket would be the warmest, and least-conspicuous, but would require two additional layers of Fabric and we are reluctant to add that much bulk. We could reduce the bulk by using MidWeight Fabric for inner pouch pockets, but that complicates the tailoring

    We are considering these changes because many people have asked for the Handwarmer pockets on the FullWeight ShirtJac, which is mostly worn like a Jacket. On the other hand, the MidWeight ShirtJac is often worn as a mid-layer, sometimes tucked into pants. And there really isn't a downside to having the Slot Buttons under the rear of the collar, even if the Double Hood is never attached.

    Here is a review published by Explore Magazine and written by Kevin Callan, the magazine's field editor and a well-known tester of outdoor products.

    And a neat comment sent to us by Bruce Carlson:  "Received my XL Lynx wool ShirtJac yesterday. Wore it to work today. 5-6 compliments….everyone wanted to 'touch' it!".
