Customer Reviews Smartwool Merino 250 Base Layer Crew

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!

Wearing with the base layer bottoms for the best post-holiday lounge wear!

I wear the base layer under a sweater for warmth for casual wear. I also wear it as my top for my Pilates class. Very versatile.

Perfect and warm to layer or wear by itself. The pattern is interesting and fun. I also love how long the shirt is so it can be tucked into your pants or left out.

My sister comes from Florida to New Hampshire every year and she freezes at Christmas time. I bought this for her. I am sure that she will love it. I live in Smart Wool all winter.

It's beautiful and comfortable. I usually wear a medium, but purchased a large. Fits great!

Great shirt, I have multiple and love them all! Great as a base layer or on their own.

Have not worn it yet, but it washed well. I've bought these before. One is a print and another is solid burnt orange which both have washed and held up well. I also bought the solid light blue one.That one did not do well. It pilled after washing and seems thinner than the others. Mostly a good product and I will buy again.

I like this shirt a lot, it is soft without being too fleecy or making me sweaty and is warm so it is great for layering with a vest etc. I have another Smartwool long-sleeve in the same size that fits better so I feel like this thermal in particular fits small

Very warm and durable, great for backpacking

I'm tall and have long arms and it still worked for me.

This is my second classic thermal. These shirts do really well at keeping me warm. I would really like one in hot pink.

Fits true to size very comfortable

Solid product. They stopped listing g/sqft for the material so it is hard to compare to other brands.

This is my 4th one of these tops, I knew I needed another because my first was starting to show some wear after about 7-8 years - I wear these full-time in the winter months. Love the warmth and the cozy fit and the indestructibility of these!

I usually wear this baselayer for my yoga class,several times a week. It's a very nice fit,except for the sleeves(too long). I love the weight and the color is soft. Thank you for such a good product. This is my second baselayer. The first one is at least 15 years old and I am still using it in winter. Does not show wear.

These fit great, look great, and feel great. I sometimes struggle to find wool clothing, especially base layers that aren't itchy or slightly uncomfortable but these are perfect. I bought these as a set with the Women's Classic Thermal Merino Base Layer Bottom and I'm very pleased. Barely itchy at all and are substantial enough to keep me warm but thin enough to fit underneath other clothing (like any good base layer should). While I hesitant due to the price, I can confidently say these were worth my money.
