Customer Reviews Smartwool Merino 150 Baselayer Long Sleeve

I wear these EVERY DAY! Perfect weight. Just right warmth. Beautiful colors. Love!

Have many of these. Bought this for my mom so she stops borrowing mine. The bottom hem can unraveled on my other ones.

These are nice and easy fit under any clothing for harsh winter days. I did order one size up I'm 5'2", 120, but the small was just a little too snug for me. Mediums are a bit longer but I prefer the fit.

This product doesn't look like a base layer so I had always discounted it as not "performance" enough. Boy was I wrong. It's so comfortable, can work as everyday clothes or athletic. Absolutely buying more patterns. #SmartwoolLove

Great for cold weather cycling base layer

This is a great long sleeve and I have to buy it one size bigger

Love smart wool . Wish they had more basic color options in this same body

This is a wonderful base layer. It's not too thick or thin, and pairs well with a fleece, another Smartwool hoodie, or just a sweatshirt. It is perfect for outdoor activities and is super soft. I think I read that people wore this for seven days without washing it and it didn't stink - def not the case for me. No big deal, but I get about two wears before it needs to be washed. It's definitely worth the money - I'm SO glad I bought the set!

Perfect for cool mornings with a light jacket over

This baselayer long sleeve is the only shirt I want to wear. I could wear it every day. Actually, I did for a week! I washed it out and hung it to dry. It washes beautifully and dries quickly.

I use this as often as possible. It is beautifully designed, and very comfortable. I have laundered it several times and it looks and feels just as good as when it was new.

Absolutely the BEST, lightweight, warm-when-you-need it, piece of clothing I own. I wear it year round in MI and California.

I purchased for my daughter as a Christmas gift. I love any merino wool sweater or dress and I am sure she will love the layer for the outdoor pursuits she enjoys.

I wear these for every day, for cold weather outdoor activities, even for a nice looking long sleeved shirt out on the town. Nice all around, just ends up being a tad bit tight for my liking for an xl, but i think that is the style these days.

This will be my new go-to base layer. It is a similar weight to Icebreaker 200 top but feels better. It is softer and does not seem as thin. I look forward to using it for all my winter adventures this year. #SmartwoolLove

This is a 3 season layer for me. I love this shirt so much. I can wear it alone or as a base layer for everyday or for any type of outdoor activity. This shirt is always a win. #SmartWoolLove

I'm a long time Smartwool fan. I got my first sets of 150 and 250 base layers about 10 years ago and they have held up amazingly well! I find the 150's to be slightly itchy, but have come to accept that's just something I have to deal with if I want to wear wool. I'm petite and totally flat chested, but have very broad shoulders, so women's tops usually fit strangely on me. I absolutely LOVE my men's 150 baselayer shirts and I'm pumped to see the women's version has also been restyled with a raglan sleeve! Raglan sleeves are the best!

This 150 Base Layer is lightweight, warm, regulates to body temp, well-made, 87% Merino wool. It is perfect for all-seasons. I use it all the time for active recreation and to layer under a fleece to stay warm during winter in my office at work or to run errands. It is a must-have, in addition to the 250 Base Layer which is about more than twice the weight at about 7 oz. The 250 is 100% merino wool and not as stretchy as the 150. The 150 is great for running, hiking in spring/fall, etc. I am 5'1 and 95 lbs. The XS fits perfectly. Not form fitting but fits close to skin. Definitely a staple in my gear. Very versatile and can go many uses before needing to be laundered. Does not hold odors.

Lightweight but warm - perfect! I'll wear it year-round.

Love this shirt for all year .Please make it in a v neck as well!

My husband bought me one of these for Christmas. I bought myself another after realizing I needed at least 2. These shirts are super comfortable and great for any activity or just to lounge around in. I am a runner so I love to have great active clothes like this. Perfect fit. #sweepstakes

Love these 150 base layer shirts, long sleeve for winter and short sleeve for summer. I layer them for indoors and outdoors. I have one 250 layer tunic, that I think is a little itchy. So I will stick with the lighter weight shirts year round. I took 2 of the 150 base layer shirts on a trip last summer..I wore them every day. Perfect. Would like to see more colors and more of the exploration, tunic styled, short sleeve shirts.

Comfortable and very soft material. Kept me warm as a base layer.

I use this shirt running. It chilly but not cold temperatures it works great alone. In colder temperatures it's perfect under my Smartwool windbreaker jacket.
