Jacquard CPO Shirt
Drab Green in sizes 3X and 4X are the only ones available now. I don't see more MidWeight Fabric until 2027. BUT we do have a lot of Denim CPOs ...
Please click here for the Denim CPO, which is of similar design but made with our own 100% Wool Denim Fabric. All our Fabrics are made from the same fiber, but the Jacquard and Denim weaving techniques are very different.
DESCRIPTION: The classic CPO (Chief Petty Officer) Shirt originated almost 100 years ago, and has been widely appreciated ever since. It’s a jacket or a shirt, depending on what you need and what else you wear. Our CPO is an extremely versatile piece in a basic, historical design.
FIT GUIDE: Fitted - cut closer to the body with minimal room for layering, but you can still wear a flannel shirt, thinner sweater, or lighter wool shirt with decent mobility.
SIZE CHART: PLEASE check the size charts and let's hope we can get it right the first time ... exchanges/returns are free but a chore for you and an extra cost for us.
FABRIC: 100% WeatherWool Certified Fine Wool in our MidWeight Jacquard Fabric
WeatherWool is always MADE IN USA 100%
FEATURES:
- Signature slot button closures secured with nylon ribbon on cuffs, at the pockets, and front center
- Milspec water-resistant thread throughout
- Two external chest pockets
VERSATILITY: The CPO is typically a 2nd layer but often a 3rd layer and is sometimes worn as a mid-layer or even a base-layer. Some people will tuck the CPO into their Pants. Our Fabric is comfortable enough that the CPO can be worn over a short-sleeve base-layer or even as a base-layer, particularly on warmer, rainy days.
Our MidWeight Jacquard fabric is designed with breathabilty and activity in mind. Our FullWeight or multipal layers of MidWeight is wear warmth starts to stack warm air in.
ANECDOTES: WeatherWool Advisor Leo Grizzaffi (last photo), the outdoor writer, likes to wear his CPO Shirt instead of a sport jacket.
And a neat comment sent to us by customer Bruce Carlson: "Received my XL Lynx [CPO Shirt] yesterday. Wore it to work today. 5-6 compliments … everyone wanted to 'touch' it!". People wanting to "touch it" is something we hear often about Lynx Pattern.

CARE AND CLEANING: Wool’s anti-static properties help make it self-cleaning and odor-resistant, so it should not need frequent washing. It may not even need rare washing. If your wool does not seem dirty, don't feel obligated to clean it ... even if you have not cleaned it for years. More details about spot cleaning and submersion washing can be found on our care and cleaning page.
Quality Control Steps for the CPO
MidWeight CPO, walking in light rain, temp of 66F/19C, without a base layer ... a day when the MidWeight CPO was better than anything else I can think of ... with no base layer at all!

Slot Buttons
Slot Buttons are more secure than any other type of button we know. They have two slots through which an ultra-strong strip of nylon ribbon is threaded. The nylon ribbon is very securely sewn to the garment using Mil-Spec Anefil Nylon water-resistant thread. The Slot Button design results in an extremely well-anchored Button.

Our Fabric
Our 100% American, 100% Wool Fabrics, made from 100% WeatherWool Certified Fine Wool, are the foundation of our company. Making our own Fabric is time-consuming, difficult and expensive. But for us, there is no other way.
MidWeight WeatherWool
Our MidWeight Fabric is the same as our flagship FullWeight Fabric but 30% lighter, making it ideal for those who engage in more activity—and endurance-based activities or simply need less warmth or weight in the pack. Like our FullWeight, it's produced on a Jacquard loom, which gives the Fabric a three-dimensional weave that helps insulate far better than regular flat-weave wool fabrics

FAQ
Where is it made?
All of our products are 100% made in the USA using 100% American-made wool and materials. We pay American citizens to make all of our garments. See more.
Is WeatherWool in retail stores?
No, it is only available directly through this Website.
What are your garments designed for?
We set out to make the best All-Purpose outerwear possible and we take that "ALL" part seriously. While some items may be better then others for specific needs we like to think we have the perfect garment for anything you do outside regardless if it is in the serving in military, hunting, camping, city, country, work or worship.
Why is it so expensive?
We never cut a single corner at any step. We make our own fabric, from the best wool in the USA. There are over 45 steps in making our fabric alone. We use the highest quality materials made in the USA. We have owner operated customer service on call to serve you and offer free shipping in USA and Canada as well as hassle free returns.
Is WeatherWool Merino Wool?
Not exactly. Merino is great wool and has been very well marketed over the years but pure merino alone is not actually suitable for us.
We select our wool based on a number of characteristics including micron, strength, length, and comfort factor. With the help of our advisor Bob Padula we have determined the perfect recipe for our goals. Thanks to modern equipment we can test all the wool before we buy it and that wool is primarily coming from Rambouillet and Targhee breeds.
How do you clean WeatherWool
Short answer, you almost never need to. It's self cleaning. We've had garments we've worn for 7 years that have never been cleaned other then some rain.
However, things happen. If a lukewarm bath and dry flat doesn't do the trick, you can try wool-cleaner. Our full cleaning page is here.
Can bugs bite through your fabric?
We have not heard of any that can.
What is your customer service policy?
Our customers will be taken care of.
Full Customer Service policy can be found here.

About us
Founders / Owners
WeatherWool was founded in 2009 by Ralph and Debby DiMeo. Together with their children and a few friends they maintain 100% ownership of the company. Their full story can be read here.
Direct Connection To The Source
We make our own Fabric, starting with raw wool carefully and specifically selected from a small group of ranches in the USA that meet our certification standards. This isn't no stock photo. We're actually out there during shearing sampling wool and sharing stoies and good times with the ranchers and their families.
The Best We Can Figure Out
While most companies decide a price point, and reverse engineer a garment to meet that retail price, WeatherWool does the opposite. We make the best garment we can figure out how to make at every decision we face.Although our garments seem pricey to some our profit margins are below average and you're getting more value for your money and assurance that you're getting some of the best wool in the world.
