Great base layer
Top notch base layer. Super comfortable, soft and warm. I've worn mine for the past year-ish, and the quality is very good, washing it does not shrink it, color is still good and it fits me really well. I am 6'4", 235 lbs, 36" sleeve, and I bought XL big and tall. Recommended.

Meriwool very nice!
Purchased long sleeve thermal Base layer in medium of 250 weight. After one month, it is holding up very well. Have machine washed it in cold, and hung dry and it has kept its size. It is soft and warm. A healthy, breathable fiber worth every penny. The waist is done of very high quality, wide and not scrunched, rather a fine hold within the material. Our only wish is that they came in v-neck too.

Nice shirt
Nice shirt, good weight, comfy. It seems a little large, being wool it might shrink a little. Not sure but so far so good.

Warm as toast and softer than most
The cost of a wool base layer has kept me from buying one of these for a while, but man oh man I wish I had some wool underwear sooner! I bought the long sleeve midweight crew a couple of weeks ago and I have worn it just about every day since getting it. I'm no outdoorsmen, I just hate wearing a heavy coat and work in a drafty 100 year old building so I was looking for a way to stay warmer without having a million layers on while I was at work and to avoid putting on a coat just to run to the store. Ladies and gentlemen, we have a winner. Out of the box it fit fine. I usually wear an XL and so I ordered an XL. The fit around my body is snug like a baselayer should be but not constricting. The sleeves are plenty long. I have them pushed up to my elbows most of the time I'm indoors and they are not too tight. The length of the shirt length is a few inches below my waist and tucks in and stays tucked in. Layered with an overshirt or sweater I've been comfortable for two weeks; had to do some heavy lifting for a while some days and got a little sweaty, but the wool dried quickly and I didn't feel chilly afterwards. If you haven't caught on, I love this thing. As I mentioned, I have worn it almost every day since I got it. After the first 6 days (I took it off at night to air out and figured I'd be much too hot under a comforter with it on) I hand washed it with some wool detergent and to my pleasant surprise, it dried in less than 12 hours (for anyone who has hand-washed a sweater and left it on a towel to dry you know that this is a record time). I put it on the next day and it didn't shrink at all and got a bit softer. That was 6 days ago and I've worn it every day since. I am a convert. Stop wasting your time with polyester long johns!

90% the comfort, all the performance for only 50% the price of IceBreaker, Ibex, etc.
If I had to pit this shirt against something from Ibex or IceBreaker quality-wise, I'd say it's about 90% of those brands' workmanship, but of course at about 50% (or less) the price. So, from a value standpoint, it's absolutely worth it. What do you give up? I'd say overall softness slightly misses the mark, at least comparatively. Again, it's probably only about 10% more itchy than an Ibex (RIP) Woolies shirt - not uncomfortable in the slightest, but every now and then I notice the texture/feel with the Meriwool shirt whereas I never think about the feel of my name-brand shirts. Hardly a deal breaker, but worth knowing if you're incredibly particular about your clothing's feel. The overall fit is good, a bit trim or athletically-oriented (good for thermal performance), but not too tight. That said, you're not getting the more custom-feeling, multi-panel construction from something like the Ibex Woolies. Once again, the latter shirt is probably 10% more comfortable simply because its construction is more complex and ultimately better tailored to the chest/shoulder area without relying so much on the fabric's inherent ability to stretch over one's angles and curves (merino is known for many things, but not for being overly pliable or stretchy). Everything else is on-par: fit and finish, strength of seams, durability of fabric, quick dry capability, machine wash- and dryer-friendliness, resistance to odors, etc. - it's all up to snuff. Personally, I can live with the compromise for the price; $45 for all the performance and nearly all the comfort of what would otherwise be a 100-120 dollar shirt is hard to beat. But if you want the absolute best, maybe skip this shirt; just know that in order to get noticeably better you'll be spending double.

Great product
Excellent winter shirt. Always seems to be the right temp. Much more breathable than cotton. I can wear it during the day and overnight with no issues. Highly recommended

Size down if wanting base layer
Really nice, soft base layer. If you are buying as a base layer you probably need to size down. I originally ordered an xl and I am 6'2" 205LB and generally wear an xl in shirts, but this was too lose to be a base layer. the large fits much better.

Es un buen producto que cumple con lo que dice en la etiqueta. Una primera compra enviaron la talla equivocada pero sin problemas para devolución. Veo que les ha pasado a otros así que podrían pone rmas cuidado que su precio lo merece.
