Customer Reviews Smartwool Merino 250 Base Layer Crew

I love these base layers, I wear them everyday in the winter under my sweaters and I also use them for running when it's cold.

Love these Smartwool crew tops and I own a little collection of them in various colors. Have noticed some colors are softer than others. They loosen up a little after some wears. Fit is athletic fit. I'm a size 10 and can wear a medium or a large. Or both for layering!!!

I live in these and have several I've collected over the years. They are easy to care for and still look amazing, showing no wear after several seasons. They are so cozy & warm that I get a little sad when it gets too warm to wear them. I am hopelessly addicted to Smartwool clothing.

My go to winter top. Purchased in many colors and patterns. Feels great in colder weather and works with layers and vests.

Wear alone or as a warm, non-bulky layer when it's cold.

I purchased this in 2 colors, in 2 different sizes. I'm a size small on the size chart, but was torn between ordering small or medium knowing it would be form-fitting. I got one in S and another in a M because that pattern was sold out in S. And I can say they both fit generally the same on me. I would go for S next time, especially for use as a baselayer, but honestly the fit and look is pretty similar between both. My new favorite shirts!

Love this! I wear it all winter for cooler hikes and trail runs. Works well with a light layer and keeps me warm without sweating.

Nice!

I exclusively use Smartwool for skiing as my base layer. They are super thin, comfortable, and warm. If you end up getting too warm, they also seem to pull the sweat away and dry quickly and not stink. I also wear them all fall and winter for biking, rollerblading, or just cool days. I'm also tall and the sleeves are long enough for me. Perfect.

Not as warm as past years. I need to wear 2 under my coat to be warm enough outside.

Love it. Thank you!!

Perfect fit, so comfy

I love these under jumpsuits and shirts during casual days off. I always bring them when I'm traveling to Iceland because they're so great to pack and I get so much out of them. Warm underwear but also cool and smart sweater under clothing when you want to pack light. These can never go wrong!

The light blue is quite pretty. It's hard to find wool clothes that aren't drab or washed out colors. The sweater fits snugly to keep you warm. Very soft. Nice enough to wear in a casual work environment.

Love the color , feeling on my skin

SMARTWOOL is THE ONLY base I use for layering when hiking, traveling or even everyday. They are by far our favorite go to's. I only wish the precious blue was back. This is harder to match up to my other layers, but I love the fit and style.

Warm, comfortable but not hot.

I wear this as my base layer for snowboarding and I love it! It's thin but still keeps me warm with my other layers. And I love the emerald color!

Fantastic base layer. I've worn this backpacking under a fleece in 35/40 degree weather and wore it to run a half marathon in 45 degree weather. Great weight to it and not itchy at all.

I love these shirts! I bought a few or them for a trip and have been wearing them all the time at home! They are comfortable and keep the temperature comfortable

I've been wearing it almost all the time since it arrived, because it's so cozy and yet also looks nice on it's ownseems like it keeps me warmer and yet is not too hot as easily as a fleece/sweatshirt/flannel. Also I really like the pattern of mountains, and how it is form-fitting without feeling too small or anything. By now I have purchased two different patterned styles of this shirt, and have noticed that one of them is much softer, which is interesting.

Love these shirts. I usually only buy one every 4 years b/c they last so long and wear so well.

This is comfy and warm. The color is great. Perfect base layer.

Love this base layer, super comfy and warm!

I was worried when I purchased this amazing top. I'm 75 years old, small boned, 5'1" 105 lbs. and was concerned that it would not be appropriate for someone my age. Not at all it fits perfectly and I will buy more.
