Customer Reviews Smartwool Merino 150 Baselayer Long Sleeve

Good quality, just too tight, hard to return to get a large

Good for wearing underneath. A bit to thin than I thought but still warm enough and comfortable.

Good shirt for layering. I wore it under a heavier wool thermal and felt ok in mid 40 degree weather. I'm 5'2" and 120 lbs. XS fit perfectly. I took one star off because the side tag (just above your left hip) is incredibly itchy.

Great fit, washed up perfectly great color and definitely a year round piece in the Pacific Northwest

Great color and fit.

This shirt is thin but sturdy to layer. My only complaint is the neck line could be more snug to the base of the neck.

Lightweight long sleeve top. Cute and fitted look! Not as stretchy as some other smartwool tops. #sweepstakes

the L/S base layer is very nice - fit was perfect. I am disappointed that this is not 100% wool - I thought that was how it was described. It is 87% wool but I like the color and it will work well.

To keep warm

Ok to layer but not as nice on its own.

So comfy. Perfect for spring and fall

Smartwool is the best base layer out there!!

I'm a Smartwool fanatic to say the least! I wear the socks, underpants, base layers, and tops year round. I love the Merino All-Season as the fit is often perfect - contours nicely without being too tight - and the fabric is breathable. One downside to all the Smartwool products that I hope Smartwool will begin addressing: the fabric could be more durable. We find tiny little holes in the shirt sleeves within a few wears and the sock toes wear quickly.

I wear this all year round. Good for hit or cold. For very cold as a base layer maybe not as good for very hot AND humid. Also the durability isn't ideal

I was under the impression this was heaver than than it is. Other than that you stuff is great

I LOVE my old Merino 250 tops, but it looks like all most of their tops for 150 and 250 (or classic and all weather or whatever their curre t naming scheme is) are low cut...when I opened the package I was upset because I assumed they accidentally sent me a V-neck. It is a little lower than the image shows. I wish they would separate this "feminine" lower cut style to the higher standard crew neck style. I wear these for warmth and coverage, not for looks. I don't want my beck getting cold! I have lower cut mens Hanes undertanks and these even stock out a lot. Quite disappointed in how low these are. Other than a cold neck, the rest is good quality. I have a comparable Icebreaker style and I love the thin but high neckline on the Icebreaker. Icebreaker also seems to have a slightly higher torso and longer arms, but I'm short so prefer the Smartwool which is only slightly long. The Smartwool 15p is also a bit thicker while remaining fairly light for higher output vs. the 250. I feel the Medium is a lot more giving in this cut and style...the smalls I have in the older 250 styles were way tight and the medium comfortable, but i feel this new style 150 medium is a big large from my expectations (so maybe the new cut in small would have worked) but still has room to breathe.

I bought two of these long sleeved base layers. The fabic is very comfortable and the fit is good. Four stars because I'd like the fabric to be a little thicker for warmth. And, given SmartWool's animal welfare credentials, I hope the product is environmentally preferable and cruelty free. #sweepstakes

I bought this base layer to replace another base layer that was finally coming apart in the sleeves, but I have worn it many, MANY times for the last 10 years or so. This is a great base layer. It is light but still arm. The only slightly negative comment I have is that the sleeves are a little short. The other Smartwool long-sleeved shirts I have are a little longer, so it may be just particular to this style. My arms are average-to-slightly-long so if your arms are a little shorter, please disregard this comment. I love Smartwool and their clothes are durable.

I LOVE the weight and the insulation it.provides. I was disappointed when I saw it.was made in China. When I originally checked the website I remember it saying it was made in the US.

I bought 2 of these. They are very, very thin. Returned the light blue because it was too sheer for my tastes. I know it's supposed to be a base layer, but if I take off my jacket I don't want my shirt to be see through. I kept the light gray because it wasn't as sheer. I like layering it under a thicker shirt for hiking on cooler days. #sweepstakes

This base layer is perfect to cuddle up with in the house or to wear underneath your top. The fit is comfortable and true to size.

Nice baselayer shirt, but thin material and somewhat loose.

The fit wasn't quite right for the price.

I got this shirt in Smartwool's new plant-based dye color Cloudy Blue Marble Wash and love it! The color reminds me of a beautiful blue sky day. I wear this long sleeve as a comfortable layer around my house, out on runs, and underneath a sweatshirt on chilly nights. It's incredibly soft (one of my favorite reasons for wearing it) and I only gave it 4 stars because I haven't owned it long enough to see how well it stands up. It feels pretty thing. However, if it's like all of my other Smartwool things, it will last me for years. I'm excited about this shirt and hope they make more like it!

This felt like a well worn favorite, right out of the package. I had only purchased 250 before and was pleasantly surprised with how soft, thin and light the 150 is. I've had this shirt for ~2 weeks and have used it as a base-layer for frosty morning runs, solo layer for 30 degree runs, as a casual shirt for work and as PJs! It is to be a more relaxed fit than other Smartwool tops and for a true NTS feel I would order a small (I am 5'5", 135 lbs, 34C/36B). The description says Slim Fit but I do not agree. I'd love to see more vibrant, fun patterns. I'll probably be picking up some of the short sleeve shirts for summer wear! #smartwoollove
