Merino wool baselayer 250
Size fits perfectly. Quality is great the fine attention to detail in the packing and information is greatly appreciated instructions for care of these base layers clear and concise. The comfort of this merino wool is not itchy or scratchy it works well for me in minus degree temps With just coveralls over top. Very pleased with production sure you will be too. I am a 32 waist I wear a medium pant. I am a 42-44 top so top is a large.

Overall, I'm really happy.
I've been wearing this heavyweight merino wool zip sweater and it's been awesome—especially when that unexpected snowstorm hit. The 100% superfine 17.5-micron merino wool is super soft, never itchy, and doesn’t feel heavy or bulky, even after a full day out. The warmth is impressive, and I love how the wool's moisture-wicking keeps me dry and comfy no matter the conditions. The fit is just right, with no bunching or overheating, which is a big upgrade from regular cotton. The packaging was actually pretty cool, and the included merino hiking socks are a nice extra. My only hesitation is about the care instructions—it says to hand wash and lay flat, but I’m tempted to try the washer to see how it does. I liked my Smartwool sweater before because you could just toss it in the washer, but that was only 81% wool. Overall, I'm really happy with this one!

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.

¡¡¡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

Muy cómoda y suave, se la ve de buena calidad solo con tocarla, ya veremos después de su uso a ver si resulta igual. De momento un 10.

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.
