Runs large. On my 4 th time wearing, 31 degrees helps but still chilly. I purchased the heavyweight set. Washes well. Does work because on 45 degree day was way too hot when i had to wait inside. I work EMS , so outdoors frequently during shift especially early morning.
I purchased a size medium top. It fits just right. Not too tight but skims the body. For reference, I’m 5’7” and 170 lbs and I carry more weight in my lower half.
Thin lightweight beanie that conveniently fits in your coat pocket or bag quite easily.
I ordered the L-XL even though i am a sm-med woman, because i do not like tight fitting beanies.
The fit is not loose and not tight, perfect.
Merino Wool Hiking Socks - (Pack of 3) Black Marble
Good so far will have to see how long they last but seems like good quality
A fly where is the softest Marino wool underwear I have ever had. Their socks are amazing as well.
I purchased the Merino Tech 100% merino wool thermal sets (320g, charcoal gray) for both my mother and father, and they absolutely love them. Truly—love them.
Before this, I had always sent them synthetic thermal underwear (polyester-type fabrics), which were fine, but after discovering Merino Tech, I realized what a huge difference natural merino wool makes. This is a complete game changer.
The fabric is incredibly soft, smooth, and gentle on the skin. My parents immediately commented on how comfortable, warm, and luxurious it feels. It’s not itchy at all—just cozy, breathable, and beautifully made. On top of that, the design is stylish and flattering, which is rare for thermal wear. They look good and feel great wearing them.
What impressed me just as much was Merino Tech’s outstanding customer service. I had a discount code that I forgot to apply at checkout (which is totally my fault), and most companies would simply say “sorry, we can’t do anything.” But the Merino Tech team was incredibly kind and generous—they honored the discount after the purchase and refunded the difference. That level of integrity and customer care is rare and deeply appreciated.
I also love that merino wool is a natural fiber. It feels healthier, more breathable, and more aligned with the body than synthetic materials. You can genuinely feel the quality.
I am so happy I chose Merino Tech for my parents. It was a gift that truly made a difference in their daily comfort, and that means everything to me. I highly, highly recommend Merino Tech to anyone looking for premium, natural, and beautifully made thermal wear.
I ordered two of these sets in a size L, not for a child but for me: a 60 year old, 4ft 10 woman of 75 pounds. Theresa are so soft anad comfortable. arms and legs are quite long, which can be a problem since the real kids tend to have short arms. But I'm buying more. Do they make a heavier version?
Bought both my husband and I the long sleeve lightweight tops. Good quality and very comfortable. They add warmth under layers without adding bulk.
I love these products. They are so warm and high quailty. I will definitely be buying more, I live in Utah where we do get cold winters.
these are really nice they’re comfortable. I love the thickness. Great base layers.
Wore these today on a run. They were oerfect. So comfortable and perfect for the run
Merino Wool Hiking Socks - (Pack of 3) Black Marble
I have several sets of base layers in different weights and love them. Because I love them, I have bought items as gifts. I had to return a Christmas gift and exchange for a different size. This company made the return so easy and fast and sent the replacement item to the recipient who moved across the country. Best possible customer service!!
Great feel and fit, just perfect weight to wear under almost everything!
Youngest grandson needed a medium instead of large. He picked the color and likes it a lot.
i have tried many many companies. these were the softest by far.
This half zip hoodie is lightweight loose fitting and sits at the hip. Keeps you nice and warm!
I’m very pleased with the weight, the look, color. Very comfortable and sized correctly.
I have many sets of the Merino Tech 165"s. The 250's are much heavier and living in East Texas, I will only need this pair occasionally. But they are comfortable and keeps me really warm.
Love, love these…… Great with long sweater or hoodie.
