Wasn’t expecting to be so pleased.

I took a chance having never heard of this brand and bought one shirt, pants, boxers, beanie, and the neck gator. I can’t speak to longevity yet but I will update if I see more than normal wear by the end of this season. What I can speak to is the incredible thermal regulation these provide, I have the 250 gram weight and they are warm but more importantly when I go inside from the cold I can wear these for hours without overheating which was a big issue I was having with my previous layer choices. I have had issues in the past with regular wool making me itchy but all of these items are up there with the best feeling fabrics I’ve ever tried and definitely the softest and best feeling thermals I’ve ever owned. I got the green color which I think is the perfect shade of a slightly dark and rich green, really beautiful color fabric. I ordered what I thought would be my normal size and the fit is perfection, perfectly well fitting without being too tight anywhere, this was another big surprise for me. Just going off of inspecting the items initially they do seem well made and durable given the more delicate nature of the fabric. Obviously high quality cotton is much more durable if that is what you are looking for and it can be fairly comfortable feeling too but it cannot regulate temperature like this wool, for me that is priceless and these exceeded my expectations for the conditions I put them through. I found this product on my own after looking at another more well known and expensive brand, I paid full price for all of the products and this is my real opinion about them. It’s hard to differentiate between 5 star reviews anymore so I think it’s important as a real customer to point this out and when a product is actually good quality or not. Read more

Keeps you warm and dry with soft wool

BrianJanuary 19, 2026✓ Verified purchase

Anyone who spends time being active outdoors in the cold weather knows that staying dry and warm makes for better days. The merino wool thermal layer is a great base layer to keep you dry and warm. The material is soft and comfortable. They are loose fitting but work well under a wind blocking pant or something similar Read more

WOW!

Rory and SophieNovember 13, 2022✓ Verified purchase

Wore these for the first time and I could not be more pleased! 100% merino wool and the workmanship is stellar! They washed and dried beautifully, no nightmare wool shrinkage. The fit is perfection, many long johns are skimpy in length, leaving a cold spot between socks and long johns, not these, perfection (and did I mention how amazing the workmanship is?). Wearing them today I did not experience one ‘wool Itch’, total comfort and there was a cool wind today yet the sun was warm…Never felt cold nor did I feel hot (and I worked in the sunlit garden). Lastly, these long johns are so cute! The navy and white stripe will be worn on an evening beach walk (Ralph Lauren, eat your heart out), also purchased a grey pair and the color is the perfect grey hoodie color. Bring on the cooler temps, this is a high quality, well made from beautiful natural warm fabric delight of a garment and should not always be hidden under a pair of pants. I’m a 5’6” female and purchased a size small. Expensive yes, good value for the $, YES! Read more

Warm!!!

WalleyewarriorDecember 20, 2025✓ Verified purchase

I got these a couple days ago and have wore them the last two days in below freezing weather here in Nebraska. I am a 70 year old male who walks on an average of 4 miles a day regardless of the weather. These are a game changer. Extremely soft and warm. I couple these with a flannel lined blue jeans and unbelievably warm and comfortable. I am 6' tall and weight 175lbs. I order a medium and they fit nice. Hope this helps? I am ordering another one today. Read more

great price without compromising quality

AJMJanuary 29, 2019✓ Verified purchase

I was hesitant at first because the price seemed too low for a merino wool product. I'm 5'7", 155 lbs, wear a size 30 in pants, and bought size M. Snug fit (not tight), true to dimensions, and true to the seller description and pics. I love the quality and texture, even after the 1st wash. I'm always on the look out for merino wool: breathable, anti-bacterial, soft, no-itching, it's as if the wool adapts to the outside temperature to keep you warm without overheating. Tried them outside on a zero, below-zero, weather weekend under a pair of jeans. Perfect! They didn't interfere with any movement, I wasn't building up a sweat during snow plowing, and i was able to comfortably continue an outdoor repair job even after accidentally spraying water on the bottom front of my jean leg which froze within a minute. Wore them on a long walking commute the next day (below freezing) and on the plane; in both cases, they kept me as i wanted to be, simply warm. Read more

Great purchase

Quinn EatonDecember 13, 2025✓ Verified purchase

Worth the price. Warm, but not suffocating. And the merino wool is soft. Perfect for wearing around the house when it's cold. I'm 6'1, 250 lbs and got XL, which was the right fit. Read more
