Merino 250 Baselayer Crew

The SmartWool Women's Merino 250 Crew keeps you warm on cold-weather adventures. The top's soft merino wool has an uncanny ability to keep you comfortable in a range of conditions, and is naturally odor-resistant for a fresh feel all day long. Its simple crew design and slim fit work seamlessly under other layers on really chilly days, or can be worn alone in cool temperatures where you just need a little buffer between you and the elements.

  • Baselayer top for adventures in the cold
  • Merino fabric is naturally odor-resistant for all-day freshness
  • Shoulder panels eliminate shoulder seams for added comfort
  • Flatlock seams prevent chafing
  • Slim fit works well under layers

Best laying piece!

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Medium

I love that its wool! An excellent layering piece - my whole family wears them - crews, leggings and 1/2 zip long sleeve tops. And if you put them w jeans - great for hanging out too. Easy to wash and wears well after numerous washings. Might get minimal pilling so wash w similar pieces. I have tops in med and large; sometimes I want room and sometimes need fitted.

Love it

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Large

Much better in person:) looks so good on! Just perfect! I didn’t want to take it off. It’s nice and warm and perfect for layering. It looks so good on, I wore it to go to a pub the day I received it:) buy it!!!

Every Day

  • Familiarity: I've put it through the wringer

Comfy enough to wear every day and performs great as a baselayer. I recommend this for some many uses.

Merino for the win

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Medium

If you read my site wide reviews you will probably get bored with how much I hype up Merino wool, but I will never get bored of wearing it. Merino is the warmest yet thinnest fabric and keeps me toasty on bitterly cold days on the slope, and when it's hot out, it's breathable and wicks away sweat and moisture. Since the fit is slim, it doesn't clump up under my other layers. I don't personally find it itchy. Wash in cold and you'll make sure it doesn't become itchy.

The best

    This top is very nice! It just has a very flattering cut! It looks awesome on, much better than on the pic. I am tall (5’11) and it’s long enough and the sleeves too! I love this top, didn’t expect it to be this good!:) buy it!!!!

    Perfect Base Layer

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size
    • Size Bought: Small

    Bought this for my sister in law. She is new to Utah and has always lived in warm climates. She reports that it is the perfect base-layer under shirt for skiing, fit is true to size and material is super soft and comfortable for all day in the snow

    My favorite top!!

      I recently relocated from the south to the upper Midwest right in time for winter. Needless to say I did NOT have the appropriate gear. So I researched base layers for several days and landed on this top. It was on sale so I ordered two. And now I want them ALL. I haven’t found a job in our new town yet, so I quite literally live in these shirts! They’re wonderful and cozy to wear around the house, and easy to layer on top of for when I venture outside. My only complaint is that they hold on to hair... I’m a woman with long blonde hair and I have a white dog... not the best combination. I don’t think it’s a flaw in the product, though, just annoying. I’m a true small, and the small fits perfectly. 10/10 would recommend this top. You won’t regret it!

      Itchy, but warm

      • Familiarity: I've used it once or twice and have initial impressions

      Wore this out on a day of snowboarding. It was too itchy to wear this directly against my skin, so I wore a thing long sleeve and then this and then my jacket. I was nice and toasty.

      great base layer

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: small

      Love this base layer. I have worn it skiing. It is soft and fits well. Keeps me warm in very cold conditions. Highly recommend this product!


        I'm normallay a Patagonia Capilene underlayer kind of girl but I tried these along with the matching bottom and was pleasantly surprised. The top fits snug and is farely breathable with a good amount of stretch + super soft. Would recommend

        Disappointed with the material

          I bought this item based on the reviews. People raved about the material being soft and not itchy. The item is soft to the touch with the hands, however once the item is on it was itchy. I returned the item and decided to go with something else instead for my trek.

          comfortable and stylish

          • Size Bought: XS

          I love this shirt. I've worn it out to dinner, under and over other shirts and jackets, and I've worn it as a pajama/loungewear. Very versatile, but the dark green color is very stylish and the fit was very flattering.

          Breathable and warm!

            This baselayer offers warmth but not to the point where you overheat. The material is breathable and comfy. Not at all itchy like most wool. 10/10 recommend!


            • Familiarity: I've put it through the wringer
            • Fit: Runs small
            • Size Bought: small

            This is one of my favorite shirts for skiing on cold days, or any day at work. It is quite warm, so I recommend saving it for sub 20 degree days on the slopes, but it can be worn casually any time during the cold months. The fit is really flattering and it is quite soft for a wool shirt. One thing I wish is that it had longer sleeves. Try sizing up if you have long arms.

            Great base layer

            • Fit: True to size
            • Size Bought: small

            This is one of the best base layers. The fabric is so soft and warm. It wicks moisture well and is truly odor resistant. I am 110 lb and not a fan of tight fit; found small fits very well - not sung and looks slim. Awesome.

            Amazing Shirt

            • Familiarity: I've put it through the wringer
            • Fit: True to size
            • Size Bought: Medium

            I own this shirt in five different colors. It is the perfect base layer because it wicks moisture and doesn't become smelly. I have worn this shirt as a casual top, as a base layer when skiing, as a pullover when biking, and as pajamas when camping. It is my favorite go-to top. I am 5"10" 140 lbs and DD cup and the medium fits perfectly.

            Super Soft

            • Familiarity: I've used it several times
            • Fit: True to size
            • Size Bought: S

            Review from Keri Schneider: These shirts are wonderful. Great fit, not too snug and not too loose, and they get softer the longer you wear them.

            • Size Bought: Smalll

            Kudos to backcountry.com. My order of the smartwool top was cancel. Cool rep made it right by ordering another. The item is soft, breathable and totally magical! When it is on with a thin comumnia jacket, it made my backpacking trip in August at Point Reyes easy. I am 5”7 and half. 143 pounds. A small fits me.

              How to Measure:
              For best results, take measurements over your underwear.
              Measure under your arms, around fullest part of chest and back circumference.
              Measure around your natural waistline, keeping the tape a bit loose.
              High Hip:
              Measure around high hip circumference approximately 3-inch below natural waistline.
              Stand with feet together and measure around the fullest part of the hip.
              Arm Length:
              With elbow bent slightly, measure from center back of neck, across top of shoulder, to elbow and down to wrist bone.
              Measure along inside leg from crotch to ankle bone. Or using pants that fit well, measure the crotch seam to the bottom of the leg.
