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 upon what you need and what else you wear. Our CPO is an extremely versatile piece in a basic, historical design.
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.
Overall, the 100% Wool Denim has been surprisingly weather-resistant and durable. I think it's a little less weather-resistant than the MidWeight but people who are not used to our wool have been very surprised by the performance.
WeatherWool Advisor Leo Grizzaffi, the outdoor writer, likes to wear his CPO Shirt instead of a sport jacket.
Features
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.
WeatherWool Denim
Denim is a high abrasion—and tear-resistant weave, making it a staple in workwear. Instead of using cotton, we produce our Denim from 100% WeatherWool-certified Wool. You'll find our Denim to be much softer and cozier than traditional cotton denim.

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.
