Customer Reviews Smartwool Merino 150 Baselayer Long Sleeve

I did size up because people said it runs small. I could have gotten my normal size, but I am ok with a looser fit. The sleeve length is very long however (and I have long arms), but I'll see what happens when I wash it. Overall, love the print and it is very comfortable. I like that it looks like a T shirt but is warmer.

Need to wear under a sweater so may try the 250 base layer

I bought two of them as gifts; one for my daughter and one for my daughter in law. My daughter in law said that the sleeves shrunk, and that it is a bit itchy but overall she likes the weight of it and its warmth. My daughter has not mentioned that hers shrunk, but she does like its weight and warmth also.

Seems to run a bit large, but otherwise great quality.

I'm 5'4 and weigh 123lb and ordered small. The size is just right. However, I wish it was more stretchy. I liked it enough that I kept it.

Great for day to day cool weather. My biggest con is that every piece of Merino 150 I've owned gets holes so easily. I stitch them back together or just live with the holes, but makes the piece limited to non work (I work in the outdoor industry) attire. Performance however is always on point, and I love wearing 150 in the spring and fall. #SmartwoolLove

I wear this for running. I can wear it for a week's worth of work outs and hang it up in between and it doesn't stink. Compared with the rest of my work out shirts that I wear once and wash in a separate load from my regular clothes... Itchy though (I have sensitive skin)

In comparison to my smartwool sport 150 short sleeve tops (2021-22), this one does not come close to it with respect to odor resistance. Soft, quick dry, good long length & the sleeves. Not certain if I could recommend it, only because odor resistance is coming up short. I'm debating whether to take it on my 10 day hike.

Fabric felt a bit rough, decided to return it. True to size.

I love this base layer because it's lightweight and very versatile. I gave it 3 stars because the stitching on the sleeves seems to be unraveling, even before it was washed. I washed it on a delicate cycle in a mesh lingerie bag to prevent more unraveling, however I am disappointed in the lack of durability. I have many of the thermal merino base layer tops that are incredibly durable.

Great quality as always but returned because the cream color showed thru to the bra, I think I need to purchase the thicker 250 next time. Also why do you no longer go by 250 or 125 in your description?

I have four of these shirts. After less than a year, all of them have holes in the seams at the armpits. It's a shame because these overall are the perfect shirt for both summer and winter. For the price, they need to last longer.

I have another smart wool base layer that I love. But the new one is much thinner and has a very irritating hanging loop at the back of the neck. I had to remove it in order to wear the shirt. Unfortunately it was sewn on very tightly. Not sure I would buy this particular shirt again.

I was looking for off white / ivory and online looked perfect but "natural" is really very soft yellow. Had one from last year in off white but shrank and gave to my daughter who loves it. I should have ordered the next size up which I've done in other base layers and all are great in the colors I ordered. I would like to buy off white / ivory. Thank you for good quality. I live in cold rainy Northwest and really appreciate your base layers. Maybe need some pretty, flattering colors.

I wear these all the time. However, I feel like the new ones are cut different. I have the same shirt from 2021 and it has a more fluid fit. What's nice about the old fit is it doesn't cling which is important in the hot Florida sun...yes, I wear my old smartwool shirt during the summer. Customer service suggested I purchase a size up if it felt too clingy, not sure yet. But I do wear the new clingier version during the winter.

A solid piece but a bit expensive for an "all-season" this item will have to be worn under something else as it is too thin for modesty. I would not be able to wear it alone, with or without a bra, as you will be able to see both. It fits well and was comfortable. I noticed no difference with other long sleeve shirts regarding odor resistance, I wore it for 24 hors while traveling and could smell it.

Color of product is much darker than portrayed on-line.

Nice top, but the sleeves are a bit tight so unfortunately will be returning

I love these shirts, and wear them all winter long. But every one I've owned has worn through on the elbows within a few months. So disappointing because otherwise they are great.

It's just okay, nothing great about this overpriced base layer.

I used to wear the old style, with set-in sleeves, all the time as a classy-casual top. I travel a lot and it was wonderful. The quality of the fabric remains great, but I now wear the base layers as base layers only, sadly. Beautiful color!

I miss the previous 100% Merino shirts, same design. Not as flattering now.

Great quality. Thinner than expected. Wish it was thicker! I have the same shirt from 15 years ago that is better quality

I have a few merino base layers from several years ago. Which I love. The old ones are worn out in some places but I wear them often so I ordered 2 more. They just arrived and it seems like the weight of the fabric has gotten much much thinner which is ok but not great.

There's a time and place for every weight of Merino, but this one wasn't for me. So thin, I feel like a less expensive sportwear fabric blend will be fine for me. Like other reviews, I found it a bit scratchy. I did note that the writing on the inside of the shirt did say Merino 250 but I am certain it's 150 weight because the hang tag said it, and I ordered a Merino 250 as well which was considerably thicker.
