Bought two colors!

I have this top in red and cypress green and they may be my most worn wool items (from a girl that loves fine wool). The cypress is a beautiful color and I wore it nearly every day on a recent trip to the mountains; it was my base layer under a flannel shirt. This wool is so soft and comfortable that you won't want to take it off. On cooler days, it's my running shirt but it's my "everything" shirt generally.

We couldn't agree more - the wool is so soft and comfortable, it's hard to take off!

We hope you continue to enjoy wearing it on your many adventures.

Near-perfect shirt, impractical neckline

I'm delighted with so much about this shirt, including the odor-stopping capabilities, soft and thermoregulating wool blend fabric, and the lovely Cypress Green color. I also love that it was made in the U.S. with attention to sustainability and ethics.
During a recent trip overseas, this shirt endured salty ocean spray, bug spray, and long, sweaty hikes, but was still odor-free and fit to wear out to dinner 5 days later without washing--impressive!
As someone who burns easily, the 40+ UPF fabric was a key selling point, and the shirt fully protected my arms and torso; however, the neckline was so wide that even a wide-necked sun gaiter didn't cover all the exposed skin. I'd pay twice as much for a high-necked/quarter-zip version (and additional colors, such as rust orange and teal, would be a bonus)!
Fit-wise, the sleeves were the perfect length, the shoulders fit well, and I could have used a little less fabric around the waist. (For reference, I'm 5'3", 117 lbs, and I purchased a size small.)
The only thing keeping me from replacing my entire upper wardrobe with these shirts is the wide neckline, which though fine for indoors, is inadequate for outdoor/everyday sun protection.

Love all of your products!

The neck warmer and the shirts are perfect for added warm but don’t get overheated in them. Light and breathable wool. Have given a lot for gifts and all love them too. Even though they’re all in different parts of the country. Great product and love supporting small businesses!

Great wool shirts

My wardrobe has every color. They launder well and hold their shape.

Base layer

This material is so soft and feels like great quality! The complaint I have is that the neckline is not conducive to wearing a sports bra and really not a fan of having my bra show. Also the navy color is really almost black. Otherwise nice piece.
