Customer Reviews Smartwool Merino 250 Base Layer Crew

Quality material for all outdoor pursuits, sizing is very accurate

Up in the North Country it is great for another thin layer that adds a lot of warmth! Very comfortable and great fabric!

Just as comforting as a kids favorite blanket.

I had this while backpacking in Amsterdam and Belgium and it was perfect. Light and warm, can get a little wet and still stay warm. Perfect under a base layer in wind and rain.

Very warm and great fit!

I bought this as a gift for someone who spends a lot of time outside in cold temperatures. The recipient was thrilled with it!

This is a reliably great base layer. Husband loves it, has two, charcoal and burgundy, and birthday is perfect time to add another color. At this point, it's just about the colors; can never have too many. He wears it for both outside work and hiking, finds it a little warm for indoors (even though our house is old and a bit drafty).

Great fit (5'6" 155 lbs and the medium is perfect) and nice and thick. Haven't used it yet, but it passes the eyeball test.

A tremendous product

Wanted to try something natural after using UA base layers. The UA base layer is 100% synthetic and feels gross while sweating. Also going from a outside cold environment to a warm inside environment was unbearable. I have none of these problems with my new Smartwool base layers. Comfortable, breathable and wicks moisture away better any material I've ever worn. I'm definitely going to try out the socks now, lol. #sweepstakes

This is a very comfortable shirt. I have now bought four of these shirts; they are so soft and not too bulky to wear as an under layer.

Love this base layer. We have bought many times!

Nice mid layer to add to my collection. Kept me warm while backpacking and the temps dropped

This layer is so comfortable and warm! These smartwool long Johns are the best in the business and keep you warm and toasty in even the coldest days!

This is great Wore as a light weight sweater on a trip to Niagara Falls. Kept me comfortable even when wet.

I wear this as my first layer. It feels great against my skin and allows other layers to easily slide over it. Very comfortable and warm

Primary use is snowboarding, warm and comfortable, a great moisture wicking base layer.

This crew served as my mid-layer during my winter hike across Spain. I thrived in cold, wind, rain and three snowstorms and this crew performed magnificently. It didn't stink after a week without washing and when I did wash it, it was in a sink and I was able to wring it out and hang it up to be dry the next morning. This crew is now a foundational addition to my kit and will never adventure without it.

Great base layer that keeps me warm in damp, wet, cool Seattle. I love the baseball colored sleeves.

Comfy, warm but also can be worn when its hot. Great fit. Easy to own.

This is comfortable and good looking. It's perfect by itself for slightly cool to slightly warm temperatures.

This is a replacement for the identical item that I've had for several years. great for base layer for my skiing

great product

Superior to all other baselayer

Very soft, well made, fits well, feels great. Perfect!
