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.

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.

A great choice for thin comfortable layers that keep you warm
I don't always write reviews and I really should because I use them. I bought this wool base layer as something to wear for an upcoming trip to Anchorage and Fairbanks, but I've gotten to try it out as my area had a recent snowstorm with single digit F temperatures. This under regular jeans and a thin sweatshirt then my heavy coat made me comfortable outside and slightly overheated shoveling. It's nice and thin, the shirt looks like a regular shirt but the sizing of the leggings on me are a little baggy to look good on their own. They go under jeans really easily so that's not a problem for me. I love that they give a pair of socks with purchase, those are really nice too.

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.

Worth it!
Warm, thin base layer. Not itchy or uncomfortable even when active. Fit well. Seem true to size. Limited shrinkage following laundering recommendations. ‘Free’ socks were a nice bonus- note that the socks are heavier and are not as fine a knit. Pricey yet worth the warmth they provided.

Soft after you wash it—3x a charm! Durable and warm. Tops can be worn on their own.
When I put on my first pair of Merino.tech wool I thought reviewers had deceived me. They were much scratchier than I anticipated. I ordered two to test, but sent one pair back (I felt guilty returning the pair I tried on...yes I did wear underwear beneath, but still.) I decided to grin and bear it. Flash forward ... one wash. I immediately noticed a difference in the fabric. It was much softer. Not as smooth as silk, but not scratchy to the point of distraction. Two washes ... They were comfortable. Still not silk, but I could wear them even under tight fitting clothing and they were fine. I reordered the pair I returned. Three washes ... so cuddly! Not silky, but soft. On doing some research I found that sizing is used in wool to make it easier to work with—think starch. Starched underwear (or base layer, or whatever) is not something you want next to your skin. It takes about three washes to come out. I bought four pairs in the end, three in medium weight, and one heavyweight, and wear just about everyday (it's cold this year!) The fabric is breathable (so important ladies...ahem). It doesn't retain odors. The heavy weight pair is the softest of all. I wear them as jammies. Hubby loves them. Kids aren't scandalized when I pad out in the morning in them. I am recommending to all my friends and family members. The only thing I think you might want to worry about is if you don't live in a place that is really cold, or if you wear them under clothes into an office, you *might* get too toasty.

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.

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.

J'ai eu l’occasion d’étrenner cet ensemble de qualité pendant la vague de froid récente. Efficace et agréable à porter. J'ai dû le porter environ 36 heures sur moi non-stop comme une deuxième peau, je confirme qu'il ne crée pas de transpiration ni d'odeur. Vu la densité de ce tissu, il est évidemment un peu long à sécher à plat après le lavage à la main, mais peu importe, j'ai envie d'en prendre soin vu comme il prend soin de moi

I bought this set for a trip to Iceland and wore for 3 consecutive days in cold conditions. Kept me warm even when my trousers on top got wet. Runs slightly big but I prefer this for hiking and layering. I’m 5ft and the leggings run long, easy to roll up though. Quality is excellent and overall it’s good value for money and merino wool is the best for keeping you warm!

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!!!
