Customer Reviews Smartwool Merino 250 Base Layer Crew

I wear these under sweaters or as a top without a sweater. Most comfortable top in my closet.

Great product. Especially during these winter months. Would definitely buy again!

I been wearing these products for years and will continue to buy again and again.

The fit, feel and design is excellent, cozy and flattering.

I love this top as it fits close to the body for additional layering and warmth. The colors and design go with a lot of my pants and tops, making it very versatile. It is go to base layer for me.

As a base layer during winter activities, or as a cute top to have under a vest.

Great for keeping warm under a sweater or shirt, even a button down keeping it open

Need to remember NOT to put in the dryer.It lasts a very long time when not put into the dyer.

I size up one size on these tops because they're very fitted. Once I learned to do that I've been very happy with them!

Every Smartwool product I have purchased to date has more than lived up to its description. So - when planning an upcoming winter backpacking trip, I splurged on a set of thermal base layers. After my first day of below freezing temperature hiking, I came home and promptly ordered another set. My base layers kept me warm without making me hot and sweaty. Looking forward to being comfortable on my January hike.

I'll be using as a baselayer to keep me warm during runs when the temperature dops below 20 degrees Fahrenheit.

This is a go to first layer for me in the late fall and winter. It's warm, comfortable and easy to put a layer on top of.

I've worn Smartwool base layers for years. I wear a medium in most tops, but smartwool seems to run small. So I just order up! A large is still form fitting, but less tight under the arms than a medium would be on me. I have a long torso and long arms, so I only wish there was a tall size that added a couple inches in length on the torso and arms, WITHOUT changing the slim fit. Still, it is my favorite baselayer all winter, as well as for bed on cold nights!

Keeps me warm around the house. Great for layering under a sweater or jacket.

I have worn this base layer around the house and for casual outdoor activities, so haven't put it to a real test yet. But so far I love the color and how it fits. Sometimes base layers can be sooooo skin tight that they are uncomfrotable to wear on their own, but this one is not like that! It is flattering and fits great, and is soft and warm. The only thing I am concerned with happening is the cuffs/sleeves stretching out if I pull them up, as they are already a bit loose. But not a deal breaker, and would not discourage me from wearing it. Overall, nice baselayer and excited to test it out in Iceland in the spring!

I like the look and feel of this top. The Smartwool baselayer pants that I have in this style are warm and cozy; I assume the top will be as well. If you have highly sensitive skin, you may feel a slight itch, but it's not bad.

I have 6 of these now & absolutely them! The best for New England winters. Top notch quality as usual from Smartwool, Thank You so much!!!

If you layer up with Smartwool, it feels like "winter doesn't exist." Start with this 100% merino wool base layer, throw on a cotton T-shirt (or whatever) for style, and then add a Smartloft jack (or Active Fleece Full or 1/2 Zip) on top. It's amazing how effective they are together. For sizing: I am 5'6" 120 lbs. I take a small in the base layers, but medium in any jacket. (For extra mobility and comfort in the legs though I have switched to a medium in the pants base layer. The waist band is less restrictive and more comfortable.)

Really comfy. Not super thick but warm enough for a base layer. Only con is that every little dog/cat hair clings to the fabric like crazy.

Perfect fit! Comfortable with a light airy feel. Great as an underlayment in cold weather. Doesn't bunch up or feel bulky. Wicks away perspiration and lets air circulate on your skin. Love Smart Wool!

Adorable pattern. Very warm!

Can be worn as a base layer or under blazers

Love these shirts , but one a year, I do like my clothes loose so sized up to a latge

My new favorite top. I want to wear it under everything and looks great even on it's own

love the fit and style!
