A Gift That Truly Made a Difference
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.

Best Unders Ever!
These unders are so comfy!!! They are super soft and warm. Definitely run large so you could probably size down, especially if you wanted a tight fit. Skied all week in single digits and have stayed warm, dry, and smell free, unlike synthetics! I have washed and dried them, they are holding up great and did not shrink.

Great product! Runs small, so size up.
Good thick quality, and soft, not scratchy. Runs small. I’m 5’2”, 107lbs and the medium top and medium bottom fit perfectly. The pants bunch up a little at the bottom so they’ll work if you’re taller too. I got the 250 midweight in teal. The color is deep and rich. It was in the lower 50s last night and these kept me comfortably warm and dry in my sleeping bag.

Worth it!!
I went to Iceland and this set was great for the weather. Not bulky at all as an under layer. Expensive but it was worth it. The design and color are great and you can also use it to sleep if you need to. It fits really well too and fabric is soft and not itchy.

Inconsistent, but if you get a good pair this is a great base layer!
I bought multiple pairs to try the fit, softness and warmth. Found that the 250 for women was not as soft. In fact, they are prickly and itchy. But, I got my husband a 250 blue pair, it was pretty soft. Not much different to him to his 320 black. My 320 army green is super soft. Cashmere like. Very warm. Bought the 320 black, very itchy. Hate the socks. They are itchy and rough. I would rather pay cheaper price than get the socks. I bought the gaiter from same brand, hate it. They are thin and rough. Not recommended. Size is true to fit. With a small being very closed to your body. If you want some room around your midsection, size up Overall, I give 3.5 star to 4 star for inconsistency. If you happen to get a good soft pair, keep it!!! It is as good as smartwool, helly hansen and all those nice base layer.

Perfect fit..comes with socks too
Received it today. If you get the 250 black do not size up, it's true to size. It's soft, not itchy, didn't wash yet, but it's perfect. Great to layer or wear alone, I needed a healthy, breathable fabric and 100% wool fit the bill. The socks that are included and also warm and comfortable.

Love the quality, fit and warm + the fabric is yummy!
Almost as good as the ones I bought in Norway! I'm so happy with this purchase. I work in extreme climates and need something durable, comfortable and warm. I am surprised at how satisfied I am at the fit and comfort because I'm highly particular about fabrics.

Warm cozy and functional
Best layering and best home clothes! I’ve been using merino tech for years. Gifted for layering to many of my family members. We all enjoy and just recently my husband asked for another one for this winter. I recently purchased a set to wear at home. I got 250 and wear it as is, sometimes a put a cotton sweatshirt on top. I spend a lot of time at home with the baby and it’s important for me to feel comfortable and warm. So this is great. Was considering to get 165, thought 250 would be too warm, but 250 works out just perfect. I got it in teal color and it looks charming, deep beautiful color. From another listing i got some socks and they’re also great. Amazing combo for those who spend a lot of time at home. Or for really anyone for layering. Also, since it doesn’t hold the smell, I don’t wash it that often. For home wearing I decided to size up and it worked well. I’m always amazed of merino wool properties - warm, not itchy, cozy and aerates so well! As for me, I enjoy.

The set of Merino Women"s Thermal Underwear Top and Trousers was a perfect choice and it is just as described. It also came with a pair of Merino wool socks included. The color name is 250 Natural Merino which looks great, the quality is according to my expectations and the outfit is really warm and pleasant to the skin. I definitely recommend it.

Ich habe gerade das 2.Set geliefert bekommen. Habe es fürs Campen im Herbst/Winter bestellt. Ich trage normalerweise S/M im Alltag. Diese Sets habe ich in Größe M bestellt. Sitzt etwas lockerer. Für mich gefühlt noch wärmer durch die leichte Luftschicht.Einmal in 320 g und jetzt noch ein Set in 250 g dazu. Die Socken als Zugabe sind super!! Damit sind für mich, als echter Frosti, ein Spaziergang am Strand bei Minustemperaturen und starkem Wind ein warmes Vergnügen. Tolles Preis/Leistungsverhältnis. Es muss selten gewaschen werden. Besser ist gutes Lüften. Keine Geruchtsbildung. Waschen ist aber auch kein Problem. Ich nehme das Wollwaschprogramm mit Wollwaschmittel , 30° Grad und nur 600 Umdrehen. Damit ist bei mir noch nichts eingelaufen und die Qualität ist gleichbleibend toll. 100% Weiterempfehlung von mir!!!

Fidèle au descriptif, répond totalement à mes attentes. Pour ma part, commandé en L pour une taille habituelle de 42 (haut et bas), taille parfaitement, tel qu'indiqué dans le tableau des tailles. Les coupes sont très bien pour moi.
