Customer Reviews Smartwool Merino 250 Base Layer Crew

These thermals put all others to shame - Incredibly warm and comfortable, I've already ordered another pair!

A world of difference compared to other under Armour/ synthetic base layers. Amazing temperature regulation, can withstand serious wear and tear with multiple days on the slopes to hard days working outside. My husband also wears this simply to lounge for days because it's so comfortable (and rarely develops bad smells!)

Comfortable, warm, breathable. I was on fence about this purchase for a while but I'm glad I finally made the purchase. I'm relatively new to layering and Merino wool really is a game changer.

First time using this base layer for skiing. Extremely comfortable and warm. It was the perfect thing for my ski trip at Breckenridge.

Excellent product!

This base layer shirt is a favorite,my brother loves it. This is the second time I've given it to him .

Used on Utah ski trip in 5-10 degree (F) weather, kept my feet warm and comfortable.

I love the fit and feel of the Merino wool against my skin! Such an improvement over the cheap plastic fiber base layers. The size Medium fit my 5'11" frame perfectly with room to move around. Very happy with my purchase.

Love the weight and warmth. I plan on getting a few more in different colors.

I use this as a base layer on cool mornings. It also wears well under a vest!

Not my first review on the Classic top. But I like them so much another positive comment is warranted. Soft, comfortable and a great layering top for colder days. I only take this top in 3-4 colors when traveling and it provides lots of options.

I bought this for my son who works outside in construction and he likes it.

Love this top, super comfortable and good for regulating heat.

First I have had a thermal base layer. I usually go lighter weight for all season use. Loving this piece. Fits great and is easy to layer over. This, a short sleeve light weight, and my shell are all I need for skinning and some more adventurous snowshoeing.

Form fitting with out constraining. Merino is soft and warm. I have purchased similar shirts from at least 3 other companies, SmartWool is by Far the most comfortable and best fit. Also, really appreciate the color options. I have an older crew, probably 10 years old or more, that is still in great shape. The new version appears to be as good if not better quality!

Great base layer for where I live out on the Northern California Coast. Keeps me warm in the ever changing coastal weather!

Deliciously warm. Nice fit. Worth the price.

Good fit and warm, mildly itchy with the wool but better after a wash.

10 outta 10 recommend!!

I wear this every morning when walking my dog, whether on its own or throwing on a light hoodie over, or a heavy jacket over depending how chilly it is and it is a lifesaver. Love how it fits and love how it feels. Itchy at first, but after few hours in a vinegar bath, massaging some conditioner, rinsing, and a couple cold water, air dry wash cycles, they are good to go and will be with me for a LONG TIME. For skiing/snowboarding or in the winter elements, this is a MUST.

Quality stitching and fabric is very soft and warm. Own multiples.

feels very soft on my skin and great temperature control

This base layer top is ultra soft and of very good quality. It fits as represented on the size chart, and provides great warmth and comfort on cold winter days. I would absolutely buy this same base layer again.

So far warm and comfy for winter outings. Haven't really tested it yet for warmth, but know from experience that it will be great! Light enough to not be bulky, heavy enough for extra warmth.

Love this product. So warm. Does not smell at all. Highly recommend
