Customer Reviews Smartwool Merino 250 Base Layer Crew

So comfy, like a cozy blanket for my bum.

The best base layer for warmth ever!!

I wore it for my first time skiing in Courchevel and it was absolutely amazing, the warmest I've ever felt skiing. Would buy again!

The 320 weight is fantastic. I have diabetic Neuropathy and using a 200 under the 320 + midlayer kept me warm all day skiing with -15c and windy.

My husband is a large Tall Norwegian man. He needs it to fit his torso and long arms! They are great! As we just had 12 inches of snow and he is nice and warm, even while shoveling snow and ice!

Went skiiing with the smartwool gear. The base layer stayed dry and was extremely comfortable. Great to wear for activities.

This is used as a base layer for cold days outside, and skiing mostly. Soft and comfortable, warm, and sized well for the purpose.

Excellent layer for keeping warm outdoors without making you hot indoors. Especially for walking around college campus or city streets.

Purchased two sizes up from my shirt size as I didn't want a tight base layer. This is perfect. Comfortable and warm, working outside in Canadian winter weather.

I use this as a baselayer. I've found it to be warmer than Eddie Bauer Freeheat or Columbia Omniheat baselayers (which is a positive thing, in my mind).

My husband wears these daily all through winter. We just bought more in black for work. The old ones are in practically the same condition as the new ones. They hold up so well and are so warm. He loves them!

My dad loves this!

Whether I'm dog walking or fly fishing, during winter I'm never without my smartwool base layers!

Best long underwear out there according to my husband who I bought them for as a Christmas present. He had a pair in dark blue bottoms and top that he wore for years and definitely needed new ones!

I bought it as a Christmas present for two people and they both have told me it was well worth the money. The only thing I would like to change would be the price.

So thankful we purchased this item for our military service member! Exactly the type of layer needed for warmth and movement. We'll definitely be ordering more items! Thank you, Smartwool, for being true to what you advertise!

I use these as winter base layering for outdoor play in Minneapolis. Great for cozy days at home as well!

I got this shirt as a gift for my dad, who has recently been struggling with regulating his body temperature as side effect of some medications. He loves it and says it has helped him stay warm and comfortable!

Great layer for cold weather running. Keeps me dry and warm.

Worm and soft.

We have purchased this same Smartwool baselayer set for an entire family every single year (when someone outgrows theirs) because they are the GOAT baselayers. They keep you warm without smothering you. It's like a warm hug on a cold winter's day. No sweating just solid warmth. Great for skiing or just a day in the cooler weather. Highly recommend to all.

I wore this as a part of a series of layers under my drysuit during SAR missions. Additionally, I wore this when flying commercially as a second layer over a merino wool t shirtlayers again. The pattern to the shirt and solid color variations allow for flexibility to use this instead of a button up shirt with jeans. Tempted to order a few more.

The perfect layer. This was the one item I wanted for Christmas. Better - best - betterest!

Gift for my son-in-law. He loves it. Says it's very warm and comfortable!

This base layer top is excellent. It fits true to size and feels incredibly soft against the skin with zero itch. The merino wool provides great warmth without feeling bulky, making it perfect for cold days or layering under other pieces. It's comfortable enough to wear all day and regulates temperature really well. Highly recommend for both everyday wear and outdoor activities.
