Quality!! BUY NOW!!!!
I’m extremely satisfied with the Merino.tech Merino Wool Base Layer – Men’s 100% Merino Wool Long Sleeve Thermal Shirt. The material is outstanding — soft, breathable, and genuinely warm without feeling bulky. You can immediately tell it’s high-quality merino wool. The fit is excellent and true to size. It sits comfortably against the skin, layers perfectly under jackets or sweaters, and doesn’t itch like lower-grade wool. The craftsmanship and stitching feel durable and well made. Delivery was fast, and the product arrived exactly as expected. If you need a dependable cold-weather base layer that performs and feels premium, this is a great choice. BUY NOW!!!!

Good quality, keeps you warm.
I recently purchased this base layer and I’m honestly very impressed. The material is thick and high quality. You can immediately feel that it’s not cheap or thin like some other base layers. I took it with me on a trip to Armenia where it was snowing heavily and temperatures dropped to -10°C. This base layer kept me warm the entire time. No complaints at all. It fits comfortably, doesn’t itch, and feels great against the skin. It’s warm but still breathable. I even wear it to sleep sometimes because it’s that comfortable. Cold-weather base layer that actually works, this is a great choice. Highly recommend.

Hole in one! Wait.. I'm not a Golfer!
I admitting do like this.. Previously I purchased other wool layers, but after investigating, they were only 10-20% wool and the rest polyester.. I did however, mentally think 320 weight would be heavier than it is. But definitely like it. The socks are great and fit my feet fine for being a size 14. So I've worn this randomly around the house on cold days and some nights to bed. Looking forward to some bike rides with this on when i trails are more rideable. I kept feeling something snag on the couch arm... originally I thought it was a staple sticking out or something .. but there was something on the back of my sleeve.. thought it might be sticky, and sticking to things.. I thought it was spaghetti sauce or something of the sorts (not sure how on the back of the sleeve).. but it ended up being hard, very hard, and when I squeezed it enough to pinch it in half, the fabric SPLIT. so, now I have a hole on the back of my sleeve. While this will drive me bonkers, I can't justify ordering another shirt over a hole. Sort of a mystery. while it is within 30 days of purchase, I really will not return something i've worn more than once.

Solid pick for outdoor days.
It’s soft (not itchy), fits well under layers, and doesn’t get that gross smell even after a long day outside. He stayed warm while fishing during the winter but didn’t overheat once things warmed up.

Go for it! Worth the price
game changer - I know cold weather gear and not sure why I didn't get this sooner in life. It's great, warm, breatheable, and adaptive to temperature change. Excellent for layering in multi-temp climates. Go for it - worth the price.

So happy I purchased this base layer shirt.
My first merino clothing. I hike year round and was having sweating issues in the winter from the layers I wore. I have used this shirt 5 hikes now and no sweating. I’m very happy I got this shirt. I bought a Man’s because I am a Tall Woman. It’s nice and long to my Hips and the sleeve are a great length. I also like the red goes great with my winter jacket. Came with free socks. I tried them yesterday, they are comfortable but didn’t keep my feet warm. But no doubt they will be great when it’s not freezing cold. I will check to see if they have thicker ones for the winter as my other socks cause my feet to sweat in my hiking boots. These thinner socks kept my feet dry. I’m thankful for the free socks. I also bought another shirt in a lighter weight and that one is great as well. Also not itchy. I just ordered the pants which will arrive this week. I’m looking forward to trying them out on a freezing cold morning hike. I’ll do a review on the pants purchase after I wear them. I highly recommend merino, it’s made a huge difference on my winter hike. Wish I knew about this product before.

Great price for a great layer
Great weight and keeps my body temp regulated. Bought for my NY trip and didn’t have to wear any layers other than a down jacket on top in 15F weather. Arms are a little short, which is great, but I wish the torso would be longer to be able to tuck in my pants and avoid cold winds touching my skin.

Ottima qualita e comoda da indossare. Ne ho comprate altre con colori diversi

¡¡¡Me encantó!!! Es mejor de lo que esperaba! Todo lo que se menciona es cierto: Se siente increíble, se ve genial, después de un día completo usándola, solo olía a nuevo!! Es perfecta!! Además, incluyeron un par de calcetines que también me encantan!!!... Actualización- Las otras dos playeras que pedí, llegaron sin calcetines y no los envían a México :(; Además la segunda playera que pedí, no parece tener la misma calidad, es más áspera y no parece tener las mismas propiedades

Compré la camiseta de 250 con mangas largas en talla 2XX, y me quedó a la perfección, de hecho la lana no es tan rígida qué puede inclusive quedarle a alguien más grande (aunque es fit, puede quedarte olgado, cómo una talla extra, el pago de las mangas es perfecto para alguien talla 4-5 y el pago de la camisa al frente es más corto qué el la espalda, lo cual s esperado). Super cómoda, proporciona calor y tiene buena transpiración, el color negro es de verdad negro oscuro. Los calcetines con los que llegó de regalo son super suaves y cómodos, con el grueso ideal para usarlos con mis botas Ultra de Salomon. Con el tiempo genera un poco de pelusa la prenda, pero es lo esperado.

The colour and size were correct but cetrtainly not the 250GSM (no indication given in merchandise). From my experience as owner 0f 7 pieces (heavy, medium and light), it is certainly lightweight (160GSM). The only indication is100% Superfine merino wool. Made in P.R.C Reasons for my poor assessment 1. I bought this item with the promise of discount. The seller did not honour the discount 2.Seller choose not to response to my request for either RETURN and REFUND or Just honour the promise of discount and pay me the difference I write to share with future buyers, just be careful. I thank AMAZON for allowing me to amake a claim

Love it. I took the plunge in a Merino.tech t-shirt last summer and I love it. I got this in the winter, mainly for when I'm on my motorbike. It's a top quality item. Very comfortable and warm. When worn over another merino top it's a great combination. I'm sold on merino - it is worth the cost. This is now my go-to brand for all my merino clothing. Oh, you sometimes get free merino socks too. They are also very nice on a motorbike in winter...
