I wore a light-grey and a dark blue version of this shirt on a trip to Taiwan and Hong Kong in hot and humid weather.  I found that wool, while it is amazing much of the time, is not the best for when humidity levels are high.  I found that the shirt didn't dry as fast as a synthetic shirt that I also had on the trip, it lacked abrasion resistance, and stained easily (the stains won't come out of the fabric and the material isn't strong enough for scrubbing). Also, the shirt pills quickly. I found that just by wearing a backpack and a camera bag, that the shirt showed a lot of wear and didn't look nice after only a few wearings. I own several pieces of wool clothing from three different brands, and I love the properties of wool in dryer and colder climates.  Maybe it was the high expectation that I had for this shirt, but I was let down by it and disappointed.
As a lady, decided to buy a men's shirt for looser fit for hiking. Have walked over 40 miles in a few days with lots of sweating. The shirt has no odour, didn't get soaked, was actually cool while wearing and protected me from the sun. It dried very quickly too in the places it got damp. I like that the neckline is cut higher, which allows for more sun protection. Love it.
Really, you only need this shirt for the outdoors. I own two now and even for two week trips of hiking and sweaty activity, these are the only two I bring!
Reluctantly bought prior to a 5 night bikepacking trip in Western North Carolina. My buddies all swore that a wool shirt was worth the expense. They are right: added an insulating later when it got cold, but wicked sweat when warmer, stayed stink free, and was definitely better than a polyester shirt. Happy with the purchase. And this just looks better than the other brands. One star off for cost.
I wanted something that wasn’t 100% wool so it would hold up longer. Planning on using this on a hike in Aspen in late July. Use it as a layer to keep warm under my long sleeve collared shirt. Wearing it around my house so far it seems like it will do the job. It’s a bit thicker and not as soft as I imagined it would be.
I’m 6ft, 180lbs and got the medium. It is extremely scratchy, and the overall fit is really poor. It’s way too long (covers my butt) and the arms are cut so that that stick out unfashionably, while still somehow being constricting when I raise my arm above my head. I got this on sale, and it is not even worth the sale price. Not comfortable and not nice looking. Too shiny to pass as a casual shirt.
Perfect under a hoody fly fishing on a cool morning. I go up a size for a slightly relaxed fit. I now have three of these and won’t hesitate to get more. Great quality.
I own several of these, and they work great for my purposes. I do a lot of warm weather backpacking and these keep me cool, dry quickly, and no stink.
I bought this shirt as a Christmas gift for my husband, unsure if the bright orange color would be suit him. It is actually a beautiful color and it became his immediate favorite 150 merino t-shirt (he has a few). He also has received complements from our more fashion-conscious adult kids.
I was satisfied with the way it wicked my sweat but didn't evaporate immediately with a great cooling effect. Unfortunately my wife said I looked sweaty and smelled like a wet pet.
