Customer Reviews Smartwool Merino 250 Base Layer Crew

This top is comfortable and warm. It is not too heavy and fits comfortably under my tops. I am 5'7" and weigh 135 lbs and the medium fits perfectly. I have long arms and the sleeve length is perfect. This is a great product.

I use this shirt to go hiking.

My most favorite base layers! I have them in many sizes!

A MINNESOTA staple ! I love these tops Warm, well made & a nice selection of colors. I'm 5ft - 100 lbs & wear a size XS. The fit is great Thank you Smartwool !

I live in San Francisco, which has a mostly cool climate. Wearing this top and a down vest I can deal with all weather conditions. It is great for hiking!

Fits true to size. Feels warm. I think it's going to be a great baselayer

I really love these Smartwool base layers and I have bought 5 of them in different patterns. I've also bought a matching 1/4 zip base layer in one style. The colors and designs are so vibrant, and I always get compliments when I wear them. The slim-fitting cut is more flattering than other base layers I own and I like wearing these tops on their on without covering them up with other layers whenever possible. The material is soft, lightweight and warm and never itches. Washing and drying them is easy and I don't need to wash them each time I wear them. I highly recommend Smartwool!

Such an awesome shirt I accidently ordered two of the same color on two different dates. I wasn't planning on two shirts but love it so much I'm going to exchange one for a different color.

Grey airy top that keeps you warm!

I use this as a base layer for winter hiking in Alaska and I absolutely love it love it! Washed well and keeps its integrity :)

I love the color of this base layer. I wear the bottom/top underneath my work outfit as a clinician in healthcare. I will also be wearing them skiing when I get to the mountains. I enjoy the feel, warmth and the ability to not have to wash them after every use!

I love this thermal. I wear almost daily (I purchased a second thermal to mix out). Perfect for cold wet weather

These shirts are remarkable. As someone who struggles maintaining proper body temperatures, wearing one of these daily has made my every day living, remarkably comfortable. I've bought 5.

I use this product as an undergarment for running in cold weather. Love the comfort and the warmth it provides.

Love this top-not itchy, warm but not bulky. Can wear alone, layered and dressed up or down

Needed an extra layer of warmth for early morning walks during Michigan's cooler weather months. Perfect addition Lightweight yet warm!

Hiking and everyday

It's my favorite most versatile item of clothing I own. I love to layer it in cold weather, or to create an outfit. It is warm, cozy and comfortable

This top has just the right amount of warmth, which is critical when you live in winters that get as cold as -40! Washes up nice.

This is probably the fourth or fifth thermal base layer top I've purchased from Smartwool over the years. I wear these layered under a thermal quarter zip with a hoodie on top and manage to stay fairly comfortable while spending most of my day working outside (from 20-45F) and love that even if I sweat, I my smartwool doesn't reek at the end of the day the way synthetics always do! I wear these shirts all winter and I'm happy to say that they've each lasted about 4 years with weekly wear/washing. Thanks smartwool for keeping the fit consistent, I look forward to new colors in the future as I rotate through my wardrobe.

I love this thermal! Cozy, easy care (just throw in the washer and dryer with my regular loads), looks sharp couldn't ask for more.

The fit is perfect with all the right warmth.

Fits true to size, very comfortable, and keeps me warm without being too bulky/heavy, and nicely moisture wicking. Very happy with my purchase so I ordered another.

comfortable, quick drying, and doesn't hold smell after a day of wear!

Keeps me warm and keeps me from being gross and sweaty on dog walks and hikes in winter. I would own every colour if I could, as I wear them at work too. Smartwool has the softest and most comfortable merino I've tried, and it's held up really well with daily use.
