Customer Reviews Smartwool Merino 150 Baselayer Long Sleeve

Another perfect fit and comfortable. Your size suggestions are good. I will use this shirt as a base layer leading wilderness quests and being out in the woods .

Anywhere hiking. And more

Cozy and regulated body temp super well at night while on trail! #sweepstakes

Did the England Coast to Coast walk and brought 2 long sleeve 150 base layers. They were perfect for the 15 day hike. Kept me warm even when wet, dried quickly and were soft and comfortable. Added bonus was they did not get smelly after repeated wearing like polypropylene does.

This is a quality all-season base layer. I am 5'6" 130lbs and size small fits perfectly. Wicks moisture and resists stench, merino wool is the way to go for any outdoor activity.

Super cute and super comfy! Even in the summer!

Lovely, slim fit, with arms that are long enough (XS size purchased). The fabric seems more durable that other wool base layers purchased from other makers, but O haven't had the product for long. I'll write again in a few years with updates!

My fav go to long sleeve!

I wear this as a base layer every day! I love them! Soft, comfy all year. Great colors

The comfort and warmth make this base layer a pure delight. It is perfect for transitional weather in Virginia Beach. I can layer this top and it maintains its toasty feeling.

Warm and soft. It just right for Virginia in Winter.

Makes a nice base layer. Not itchy, stays fresh. Provides enough warmth without bulk.

These are a perfect complement to any activity. They're comfortable, look stylish, and are finely made. I would get them in every color in every style--they're that good!

Very high quality and nothing breathes like wool.

Perfect shirt to wear anytime any season! Comfy and stylish!

Just took this on vacation up north to visit relatives, site it e we ith nice slacks and sweater during freezing cold weekend visit. Will also wear it for cool evenings while hiking Foothills Trail and Pisgah Forest later this month, even though it's warm here in they Carolina mountains this 150 base layer is always in my pack.

Wonderful for winter hiking base layer.

I really like this baselayer. I've been wearing to to work under tees, layered up for hiking in cold weather, for sleeping, lounging, etc. I like that the light weight adds warmth but doesn't feel too hot when activity picks up or when going indoors from outside. The seams are really well done - no bulk or irritation. I also really appreciated that the care tag was attached with a separate thread. It was easy to remove before washing. Despite wearing this nearly every day the last few weeks, I've only washed it about once a week - it stays fresh smelling and not stretched out. The color (indigo plant dye) is really rich and beautiful. This has quickly become one of my favorite long sleeved shirts, and I'll likely grab another color to rotate it with. #SmartwoolLove

I have an embarrassing number of classic, all-season base layer tops. I like everything about the them - the cut, the feel of the fabric, and best of all, the care requirements, but this latest purchase may be my favorite. The color is like being enrobed in lilac blossoms. Wearing it makes me happy - even when the weather is cold, windy, and wintery. I wear it indoors under a sweater and as my base layer under more winter gear.

I wear this for everything; running, hiking, casually, and as a base layer. It's warm when it needs to be but also does not get too hot if I'm wearing it under a sweater inside. It washed very well and became more soft. I think it might have shrank a bit, but not a noticeable amount. I recommend washing it on cold to maintain the size and keep it from pilling. I found that I could wear it quite a few times before I even needed to wash it. It's flattering and very versatile. Definitely a new go-to! #SmartwoolLove

I love this top. It is a perfect base layer!

I love this shirt for so many reasons. I have the neutral gray color. It's works w everything. The fit is loose yet still feminine. I have worn it on hikes and then immediately put on jeans and I was ready for dinner. It's super versatile. The light weight fabric keeps me warm and looks super. Thanks Smartwool for the perfect go to long sleeve !! #Smartwoollove

Multipurpose shirt for warmth, layers or fashion. Very flattering. I adore smartwool products, but on this one shirt the stitching for the label is wildly irritating and to remove it means sewing it back up. It was so annoying I had to wear it inside out. Not fashionable!

I love these all-season crews and this one didn't disappoint. Size and fit were true, color (navy blue) was as expected, and the rest of the details were as described. I'm a size small, 5'2" 125 lbs, athletic build and fits perfect as base layer all year round.

A great lightweight base layer! I got the Indigo color and the it's a very rich blue. I've worn it as a base layer and around the house so far. The fit is true to size in terms of how other Smartwool base layers fit; it's a slim fit. If you're looking for a slim/skin tight fit, go with your normal size. If you want a bit looser fit, then I would size up. Overall, a very versatile piece! #smartwoollove
